6.4L Hemi Headers + Stock Exhaust Sound | Start-Up, Revs, Wide Open Throttle

So, you're going with long-tube headers on your 6.4L Hemi, and are on the fence about whether the stock exhaust system is going to give you enough sound? Then this video is for you! This quick video compares the sound of a 100% stock exhaust system versus Stainless Power long-tube headers with stock exhaust. Comparisons include start-up, revs, and wide-open throttle on the dyno.
Hopefully this video helps!

Definitely bringing my 5.7 to y’all this year!!!

[@louisuhhh_4546]

I miss you guys posting some fire professionally edited videos!!! Can't get enough, watching more than once each of your videos 😁😁😁😁😁😁

[@NationalSpeedInc]

Greatly appreciate the words! We paused for a bit there, but we're back at it now!

[@gabrielomalley6266]

Excellent video

[@donsonbr]

great video

[@HOWBTDEMCOWBOYS]

Got stainless works and tune on my scat really woke the car up sounds great with factory exhaust

[@omarestrada1195]

Wish there was a national speed in Cali OC I’d get the stage 3 installed in a heart beat

[@downsouthtv4616]

Always great vids. I think I’d like an angle from the back on the dyno instead.

[@NationalSpeedInc]

Good idea! We'll throw a few in there for you going forward. :)

[@walt669]

My charger is coming to NC on the 2nd of Feb! I'm pumped...

[@NationalSpeedInc]

Hell yeah! We're looking forward to it as well!

[@jamarihills3781]

Hey I have a question I just bought some bbk long tube headers. I can still connect my stock mid pipes to the headers without buying bbk mid pipes? I see you were able to retain them on this charger I have a 2013 manual R/T

[@zekevlogz]

never too loud

[@chrisboyarski2719]

If I have a 2021 do I need to have my pcm unlocked to run these without throwing a check engine light? And what is install cost

[@raiden824]

Unrelated to the Charger but the topic. One of the First Mods I did to my 20 Mustang was a Borla Atak Exhaust. Reasonable around town but it screams when you rev it out. The next Mod I want to do is long tube Headers but now I'm at least looking at adding a resonator because I already feel bad about cold starts on early days.

[@NationalSpeedInc]

Oh yeah, you're almost definitely going to want to add a resonator with that combination, ha.

[@rockaveli1013]

Which long tube gives more power BBK's or JBA ongtubes?

[@mrdr_392]

do u guys instal offroad header s?

[@timyurkovich2412]

Stage 3 package with cat back exhaust and shorty headers installed? 🤔

[@DaTKify]

Soon as video started yes ❤

[@myhoodiskc]

So that clapping noise coming from the first charger is normal?

[@ximenandre1729]

Do u need to forged that 392 engine before putting headers ?

[@tedyp44]

How long does it take for a stage 2

[@southerncaliforniafreedom7927]

Hey that's the same color as my Scat Pack 392 mine's I installed Corsa extreme full Cat-Back system plus I went straight Catless midpipes system it's hella loud especially when I do a cold start holy crap I'm not for sure I'm starting to piss off the neighbors I'm definitely getting more attention and almost a scaring people while I'm driving especially if I put sport mode specialty specialty track mode

[@TreyRichhh]

With those headers do you need a tune after install?

[@seapeoplesdidnothingwrong1307]

You really should. U will get a check engine light most of the time if not and be loosing out on some power. I have heard people are having a hard time getting the tuners to take off the check engine light because of emissions.

[@Madmaxxxx1984]

Did you guys forgot to post the dyno gains ?????.....what was the difference? It wasn't even in the description of the video.

[@keithadams897]

Will I need a tune after installing the headers?

[@ced_ctx5743]

Lemme know if you find the answer this this

[@Shaker392]

You should. Unless you want to have a CEL and not have 100% of the power from heads

[@nickjoe189]

Don’t this void warranty

[@Shaker392]

@@nickjoe189 most likely yeah but not unless the dealership finds out lmao.

[@Matp345]

No power numbers?

[@392_RHINO]

My 2 questions are will you have a strong gas smell in the car and will you lose gas mileage from this? Car did sound better the first time

[@dogazz3000yahoo]

The same the pin on how you drive it on the highway I get 18 miles per gallon on back roads to a lot stop and going I get 15 miles per gallon

[@392_RHINO]

@@dogazz3000yahoo not bad at all

[@rxses7714]

Second

[@Bigsteve_392]

Stainless Power long tubes headers high flow cats 1 7/8 $1652.00.
install $1700 and Tune 93 Octane unlocked PCM and security bypass total $2600.00. Total cost rounded off at around $6k, that's for a measly 35-40 Hp gain.. SMH! 😅

[@mtq5060]

Sounds rowdy Jesus

[@onemanteam3414]

They look like shorty headers coming off and went to longtube.

[@randomshifter1179]

I’m guessing this will void my warranty

[@srdjanbjelanovic]

First

[@killerg6807]

No good gains

[@siclt1]

What were the numbers!
