I'm a 35 year A.S.E certified Technician and no disrespect to the less experienced Tech in the video however his advice is TOTALLY false for this Exhaust system.Tuning is needed when installing totally new complete exaust system but muffler delete doesn't require tuning and it sounds absolutely amazing with the 5 inch Carven exhaust tips... I myself own the 2021 Widebody Scatpack 392 with mid muffler delete and Carven 5inch Chrome Tips and FYI a mid muffler delete is COMPLETELY harmless to the performance of this car weather at top end, Mid range, or Iow speed performance... Dodge electronic system is very sophisticated and the Engineering of the vehicle is designed to alert the driver if at any throttle position that power has been compromised... The PCM will trigger the " SERVICE ENGINE SOON" light to the driver whenever any factory settings has been altered. If you noticed whenever a muffler delete is performed that there's no requirements to reprogram the PCM as a result because simply no factory settings has been compromised... Dude needs some more training on Automotive electrical systems before taking shots at folks about what and how they choose to mod their vehicles...IJS

Back pressure is a myth. Exhaust scavenging is what you want. Engineering explained covered this awhile ago. I've proved this on the dyno as well. You will NOT lose torque if you cut out your muffler, resos, put free flowing piping, etc. It may move somewhere in the rpm, but it is not lost, nor does it do any harm. If there are no sensors, you don't need a tune.
Finally someone said it , it's a myth for Godsake, IDK why ppl still believe that crap and it's worldwide thing for some reason!!!
You said it right ✊🏾
Cant that cause blown engine?
@@gottgaame no lol
@@2iBMX no engine needs back pressure in a car. The only reason the have mufflers and cats for noise laws and emissions, that's it. If back pressure was needed then you'd see top fuel dragsters with them, but they don't..

He is wrong. First, the rear "mufflers" aren't mufflers they are resonators, they change the tone so you're not getting drone where the mufflers in the middle reduce the volume. Also, backpressure comments are just completely incorrect. He might be a decent mechanic but he doesn't understand the way exhaust works.

With all due respect, this guy simply doesn't know what he's talking about. The whole "backpressure" argument is complete nonsense. Opening up your exhaust doesn't cost you in performance. Deleting the resonators and adding Super 10's increased my RT's torque and gave it a great throaty bite. Performance didn't suffer in the least. I'd guess he's telling gullible people this nonsense trying to sell them expensive catback systems.
Definitely gullible and none Mechanically inclined...
Key phrase adding super 10s added hp, just deleting res loses torque I know first hand
@@mikekendrick4586 I deleted my resonators way back when, and didn't lose any torque. Since my last post, I deleted the Super 10's and added 12" Cherry Bombs at the very end of each pipe. It is almost unbearably loud when you get on it (wouldn't have it any other way), and the mid-range is much stronger in 3rd-6th. This is the setup I should have had all along.
@@ragingskeptic9753 I saw where you did the delete then added the super 10s. I myself loss torque in my 2016 challenger manual. After 4th hear it was sluggish
@@mikekendrick4586 Hmm. That's really odd, man. I just did a pull in mine, and when I left 3rd at 97 mph, it was still pulling hard. Are you running quality gas? Try adding octane booster? If you did a reso delete and freed up your exhaust, it should have made the mid-range a little stronger. Outside temperature also has a lot to do with it, and the car will be more sluggish when the air is hotter. Try putting your windows down and running the heater at full blast during a pull (make sure AC is not activated). Does performance improve? If so, outside ambient temperature is likely the culprit.
Oh hell no, even Americans are talking about that " back pressure " bullshit. No SIR mid muffler delete won't effect anything, meanwhile CATs delete yea u need to tune ur car to get the benefits.

Great explanation about how an engine works. However, if u ever saw the inside of these mid mufflers, you’d know they don’t create any additional back pressure. They are wide open on the inside.

Yes it does

Right if it does anything it just saves weight lol
If deleting your Mids, would hurt performance or damage your vehicle. Dodge wouldve already addressed this issue. By putting out some kind of statement saying “Deleting mid mufflers will cause loss in performance and possibly damage your vehicle and void your warranty”. And there are thousands of muffler shops across America doing this. And not one mechanic has ever told me. “ Hey pal, I gotta warn you I wouldn’t do this.” The Mids on these cars are basically a straight through design anyways. Cutting the Mids off does not affect performance, only sound. Your X-pipe should provide enough “back pressure”. But if you’re one of those OCD guys that wants it clean, drop 1200 on a Borla or Corsa for a nice clean look and that “distinctive brand sound”. But if you just want some extra sound cutting the Mids off for 100-200 dollars, won’t hurt you Bro. It seems like he didn’t want to do it, and was trying to sell you an aftermarket system that he had overstocked in the back. If you ever decide to sell the car or trade your car in, keep the factory mufflers and have them reinstalled. My Son has a 2020 Charger Scatpack WIdebody Smoke Show, with Mid delete. I personally myself, like the way the stock mufflers sound over the delete. I enjoy your content Bro, keep it up!👍
I wish they were still 1200 bucks 🥲 the one I'm putting on my wb in spring was 2400 😫
So the same thing can be said about the wickerbill you have installed...you drilled holes into a perfectly installed factory spoiler for something that has 0 performance value
I KNEW IT!! I freaking knew it!! Had a mechanic explain this to me when I was 19. I had a 96' Police Interceptor Crown Victoria I wanted to put Dale Eastman exhaust on. I wanted to know why mine was going to cost $300+ when my boi paid around $100 for his exhaust. Long story short, I listened & let him to the job. Had duel exhaust coming out behind the wheels, & it sounded so good my pops was jealous, & he had GT Mustang with Flows on it. Mine sounded just as deep, if not deeper than his car. I just thought stuff had changed now that everyone was getting the 30 minute slap stick exhaust jobs on all their Chargers, & Challengers. Good to know. 😎🤝

>> If the advice is to get a tune so the car knows what is going on, then yeah sure. That is common sense.
The "car exhaust needs back pressure" myth completely goes against how exhaust scavenging works to evacuate the combustion chamber. The higher the back pressure the lower the exhaust velocity. The lower the exhaust velocity the less vacuum is generated from the headers pulling spent air out of the chambers during valve overlap. I will agree that proper materials need to be used with good welding.

Mid muffler delete is for sound, not performance.

So it will cause no harm to the car? just wondering
@@adamnelson7067 no it won’t
@@adamnelson7067 the way I look at it is this; ever see a race car or drag car running mufflers for back pressure purposes? No, they want as little back pressure as possible. The only back pressure you would need is provided by the catalytic converters anyways. It's not like a two stroke where it needs a tuned exhaust for scavenging effect.
Lol, you reminded me to look up “ Living with Jigsaw”. Those are hilarious.
Look to me not everyone gots 1,200 or more for exhaust. Thats rent or mortgage payment or money you saving for vacation or hard times. We all don't need rolex and Invicta watch or G-shock just fine. If you got da bread drop it on exhaust. Do what u want to your car just do dont up badge it lol.
@@mobent912 they don't even keep the cars long enough for that. They keep the car 1-2 years then dump it for something else. Then if they do, they don't keep up maintenance and claim shops are scamming when their engine goes out.

This guy seems to have good intentions but it makes no difference. Won’t hurt the car. I’ve cut the mufflers off all 7 V8 trucks I’ve had and both of my camaros and had no issues. Many will say back pressure is a myth.
They say not to cut on N/A Motors they loose power. If it’s on boost/supercharged then that’s a diff story
A vehicle is designed and operates similar to a human body.A mid muffler acts like an expansion chamber,so the exhaust gasses flow more efficiently.If you cut out your two lungs,and replace them with tubes,guess what,your not going to breath properly.If you do remove the mid mufflers,you replace them with a similar design,that keeps the purpose,but gives you a different tone.Same thing goes for intake tubing,if you remove the baffled tubing,and replace with straight tubing.The intake will be louder,but doing that can rob hp,the air is not flowing efficiently.All these mods,that I mentioned, are compliments to a bigger build with proper tuning.

I got a serious question. Im looking at a durango RT and i think they mid muffler deleted. What would it take or about how much to reverse it back to factory??
Alright, thanks for the information buddy. I'll be on my way to another muffler shop now. 💯🤣
My widebody is catless, and striaght piped from the cats on. None of the factors he mentioned in this video happened to me. I did get a CEL on the dash, but that was because my air to fuel ratio was off because of the cat removal. I had my tuner that I've been working with for years, tune my car and both my HP and Torque are off the scale. I would say, do some research before modding, 2nd and 3rd opinions do matter.
if u cut tha cats out did it throw ya oxygen sensor?? u got codes?
I'd love to hear the school this guy went to for his engineering degree 🙌
What kind of exhaust you plan to put on the Scat Pack! Or are you just going to go to a different shop🤔?
Long story short get a wide band afr or scan tool note your air fuel ratio at all driving condition. When you remove restrictive exhaust components you'll run more lean because air is moving through more freely which can feel like power loss so you'd need to extend injector duration - add more fuel to get back to your recorded afr. This is how you get the power which is why people say get a tune.
Some say it do some say it don't. Only thing I know is I'm riding around with my mid muffler off and the reso is next 🤷🏿♂️. Until I get the money for a Corsa.

Fake news
I have talked with engineers on similar issues. However getting exhaust gasses out of the exhaust is key. However if you go too small on a exhuast it can cause the exhuast gasses to stay for longer periods of time. This in turn will cause drops in horsepower, because it can't properly push it out and flow efficiently. You can have the opposite end as well too big of a exhaust pipe means it has less flow to force exhaust gasses out efficiently causing a decrease in horsepower. It all comes into the demand of the engine as well as how free flow a exhaust is.
Mufflers being removed has no effect besides letting those exhaust gasses out faster. Unless you can for a fact prove to me how race cars don't have a muffler yet efficiently run without any mufflers? Back pressure on a exhuast is real to extent. But usually the misconception of back pressure will cause issues if you don't keep the muffler in place is very wrong. This topic has been and always will be debated. Both exhaust pressure and exhaust back pressure are a real thing yes.
But here is a given fact should you read it I quote "The more distinctly separate pulses an exhaust system delivers, the more positive the exhaust flow is, and therefore, the more efficiently exhaust gas is scavenged from the cylinders. In reality, exhaust backpressure is a resistance to the positive flow of the exhaust stream through the exhaust system that actively prevents effective exhaust gas scavenging. In terms of symptoms, poor exhaust gas scavenging can cause engine overheating, poor fuel economy, severe power losses, and in severe cases, it can prevent the engine from idling or even starting."
Do I believe I know everything no not by any means, The simple fact will prove what's right and wrong. You may think I am a fool but why not come back with information of why I am wrong? not arguing and belittling a person because you think your right. Also from a verified engineer who designed the 392 hemi or hellcat?
I will note I have nothing against anyone I will believe what I think is right just as you will. But I never do anything on my vehicle without looking at the benefits of it first. Also you can build a nice exhaust on the cheap if you do it correctly. I agree with not doing a hack job, but then again it's not your car nor your money. So it's best to just do what someone wants and let it go.

P.S. Back Pressure is a myth is not needed to make car perform and is actually horrible for it
Yes it is. However the flows of gasses out of the exhaust is key to performance. Back pressure isn't a thing some believe it is others not. But the context it is used is completely false. You don't want exhaust gasses backing up in a tailpipe due to size. If you change the size too big it will cause the flow of exhaust gas to slow down. You will lose hp. Then too small restricts it like a bottle neck causing a loss of hp. Each engine requires the right flow of gasses otherwise performance drops.
Back pressure doesn't make sense like I said anyone can believe what they want. However, back pressure would give the notion that the gasses would flow backwards which would never be the case or a force on the exhaust gasses to slow them which you don't want. The more efficiently the exhuast gasses are forced out of the exhaust the better a engine can perform. Hence why race cars don't have any muffler. Mufflers are there for one thing sound deadening just like resonators are for deadening exhuast drone. Not for anything more or less.
Mufflers and resonators don't add power they remove hp power for quieter sound.

@@cockdieselsworldHey man I recently bought my first 2021 dodge charger rt & its been one month in and I already did two resonator delete on my charger but im worried about the "back pressure" or drone situation what would you recommend me doing next? I wouldn't like to loose hp/torque nor do I want to cause damage to my engine please help me with any advice should I install or modify anything else? god bless you man I do regret deleting the resonator without doing much research otherwise I would of invested in a better exhaust.

Him: Say all this 🙄
Me: cool story bro are u goin to do the muffler delete or not??? 😂
Definitely droppin jewels my g🔥🔥🔥💯💯💯
The man is a mechanic, not an engineer (no disrespect). The idea of needing back pressure is a myth, and he even points out no cat/high flow cat would help make power. A straight 3” pipe will make more power (MotorTrend busted this myth in a great 2.5” vs 3” comparison). And FWIW - he called the resonator a muffler…
So if this the case why is literally every race car straight piped? You want the most flow out of the motor thats how power is made. Im not an advocate for cutting up your shit like a loony with a hack saw but this is another one of those uneducated (ass)umptions because with a tune you should be making power off of cat and muff deletes not losing it. Especially on the top end where flow and rpm are king
I love your channel😂😭❤️
Yes sir!! Love it!!!
I have a R/T pretty sure the 392 is the same the mid muffler is just an open case no need for them but you put that aftermarket exhaust on and I garauntee u they’ll void that warranty and resale goes down
It doesn’t , intake , exhaust ...wheels don’t void it . Just got mine and asked

I deleted the mid muffler on my 21 scat here about a month ago and replaced it with the Dynomax Mini Race Bullets and I have noticed no loss in performance. I’m sort of OCD about that kind of thing and I would have noticed. Maybe what I did is better than just welding in a straight pipe in place of the mid mufflers. That sounds too raspy anyways. Also Have fun spending $2000+ for a full cat back system just for sound and no power gain. The 392 is optimized already from the factory so full exhaust does nothing for power.
I’m super happy with the race bullets
I’m also satisfied with my Race Bullets.
I’m really happy with mine too. Added some rumble and volume without being too extremely raspy and loud like the straight pipe muffler delete.
Give it about 4-5 months down the line when your exhaust settles. That sounds is amazing
Just put The race bullet mufflers on My 1320 challenger car sounds great And no loss of power
Great vid 💪🏾👏🏾💯
Theirs two mufflers I want for my car. $350 each and they have to be welded on. Is it still cheap?
I fell the same way, I just spent the $2,000 and got a full Corsa exhaust system. Good thing is it's a whole bolt on if I don't want to keep my Durango I can unbolt and put factory exhaust system back on. Sound is better and no drone.💪🏿💪🏿💪🏿
Hes nuts. Its the best mod I've done so far
I had a 5.7 built and to fix the back pressure issue I installed an X Pipe.
Changed my mind ! 💪🏼
Solid advice thank you. The pipes are being cut tomorrow.
😂
Did u experience any problems im planing on adding dynomax
No problems, a little more drone than I’d like. But sounds nice under acceleration
This guy in the video here is a bit crazy. Buddy of mines father owns a dodge dealership and says a lot of the hellcats they have sold have been serviced and warrantied with no concern of the mid muffler delete. I cut mine out and my only regret is I should have done it sooner .
@@207shenanigans but its not too much drone and also can i put my stock mufflers back if i cut them

"Tuning" for muffler deletes🤣
So glad I got to see this video. Now everything makes sense. Ended up blowing a camshaft at not even 50,000 miles. Luckily it still had a manufacturer’s warranty.
Vert Interesting 🤔........ or you just dogged the shit out of it bro 😂 , either way glad she was still under warranty
@@fettieteam2333 sorta kinda 😂can’t resist the pedal
Thanks bro i was thinking about doing this
damn thats very informative....cut my pipes
If a top fuel dragster produces 8000HP with 20 inch open headers, how much HP could it make by welding the headers closed and maximizing back pressure?
I have forced induction so removing muffler and resonators helps the car breathe. But I do agree if the car is NA just save the money for a quality exhaust. Or get some forced induction and the mid muffler delete is fine.
Finally someone who knows what’s up my n/A charger srt with the catback absolutely rips with a mid muff it feels like a truck lol slow af
Good shit knockout360
Back pressure is mostly a myth though. It is not a significant cause for concern; if it was 10,000hp dragsters wouldn't have zoomie headers.
What is really important, is scavenging, and the stock x and h pipes on Chargers and Challengers does that perfectly, with or without mufflers or resonators.
@PotatoeJoe69 Hey man I have a question if I replace my existing factory exhaust with a borla or corsa exhaust system will that void my warranty and is it worth installing it I just want a deeper sound and better performance by the way I have a 2021 Dodge Charger Rt with resonator deletes currently.
Mids do nothing but change tone brodie it’s deleted cats without a proper tune that hurts the car lmaoo
Good video KING very good video “ do it right or don’t do it at all”
Hey bro I recently purchased a 2019 scatpack and the dicks before me did a muffler delete and now I have a squeak what should I do?
I don't see nothing wrong with a mid muffler delete, my car sounds great with it, still have my cats and back mufflers,. I have no complaints. Best $100 I spent on Smurffet.
Say swear...everyone keeps saying they spent 100$ on the delete. Why I get charged $300. No cap...I'm pissed
@@chucko5960 word bro, I went to Bobs mufflers in goldsboro nc,
I’m thinking of getting mine done. $120 resonator delete and straight pipes

🤣🤣🤣 I like that mechanic. And he's right. I belong to a car club and I see this happen a lot. They buy a brand new Challenger or Charger 392 and the first thing they do is cut the pipes so it can be louder. Louder doesn't always mean faster!!!
Man the race bullets are like that. If you don’t have the bread to get a full cat back exhaust. The race bullets are nice for a quick set up!!!
I dont think the mid deletes will cost any low end power - on that I disagree with him. Having said that, cutting the mids off the scats wont improve your hp at all, either. It is purely a sound change. Nothing more. What I do agree with him, though, is that replacing the nicely built and high quality (and not restrictive either) oem mids with cheap parts… that cheapens the car. Have you ever heard of lambos and porsches or even m trim bmw owners “cutting their pipes”? Or replacing their high quality oem mufs with cheap loud ones? No. Why? Cos thats what ricers do. If you cant appreciate the car that you bought, then return it, dont cut and patch it. Thats for cheap hondas, done by cheap ricers. (Buying a fully built aftermarket catback, is another story, I am only talking about cheapening / cutting / patching your awesome car here). Do it proper, or keep it proper.
Where is this mechanic shop at ?
I wanna know to so I can slap the stupid out of him
