The welded thrush muffler had a pretty good rumble, but the Flowmaster 40 series had a deeper exhaust note rumble, sir....excellent demo on the two mufflers
So glad I saw that cuz now I'm going with flowmaster I almost wished over something said go to RUclips and watch a video or two I feel better now whoever had in town about you can get out now
I agree. Compared to the 40 series it has the sound i want from a distance. They sound identical up close but from a distance the 40 series is way louder than the thrush, and im not trying to piss my neighbors off when I come home from work at 11:30 at night
Both sound good. I prefer the Flowmaster to the Thrush probably because of the dual "OUTS" more so than the muffler itself. You won't be disappointed with either!
LOL..I totally get it. I just went on a search for my first subwoofer. The opinions of an old guy vs. what the younger guys want simply A'INT the same!! Found one though and am quite pleased.
Excellent job! Exactly what I was looking to hear. I personally like the sound of the Flowmaster, but it also sounded like it might have a little more interior resonance. I think I'll go with the Thrush on my '98 Suburban 5.7. It has dual in / single out factory, but I'll go with the dual in / dual out Thrush.
Thanks Kurt! With it being on a standard cab the muffler is just back from the "listening area". The guy that did the work was a Charles Manson look-a-like that said that he could do a good job and came recommended by one of my sons. 250.00 later(counting the 40 series) I had an exceptional job, complete with index finger size perfectly crafted hangers. I have since told quite a few people about him. I love the rumble!
Exactly what i was looking for! and same engine as me. I went with the Flowmaster simply because of availability but i would have preferred the thrush so i could sport that woodpecker sticker.
This is exactly how a comparison video should be. Damn near side by side comparison, no chit chat in between. I personally want to hear the products in hopes of making an informed purchase, not a bunch of talking in between.
I'm a Flowmaster guy. Time after time Flowmaster just brings out the best in a given car. The Thrush was very good and if I never heard option #2 I would have been ok with it, but Flowmaster wins again. Even if by a narrow margin.
It is a fairly small difference for sure. I still like romping down on the throttle and hearing the purring roar of that new 350!(AKA 5.7!) Big difference with the two out situation.
Honestly, not a whole lot of difference in sound. Probably the real question is, what do you want to pay for? One is aluminized steel the Thrush , and the Flowmaster I think is stainless. Stainless should last longer. Im soon putting some exhaust on my 99 Tahoe not sure what Im doing yet. I believe my cats are clogged, so I ordered the replacement cat assembly by flowmaster. I hope the doggyness will disappear when all done. I also have a 93 1500 w/4.3 and put a super 44 on it. It sounds good at idle but still sixy when rev. I had issues with my hopped up 4.3 and pulled it. It sounded like a 8 at idle, and good cam tone with the comp cam it has in it. I think a cam lob jacked up on me or something so pulled it and threw in a doner that runs good enough.
@@Moss7202 I ended up finding out, the exhaust shop I went to was a crook. My cats were not clogged, but the most rear cat was gutted. On the 99 Tahoe there are two cats, and the one that sits more to the rear is the easiest to steal the guts at the mount bracket where rear/front half exhaust meet. Went in for a leak at that connection, ended up with a gutted cat. The cat that sits more forward and hardest to steal inners was still fine. I wasn't sure at time, that he stole it, but my 93 1500 w/4.3 was also worked on by this guy, and recently I notice right behind the cat, where was solid pipe and absolutely no leaks, their was a pipe coupling on it with clamps. I thought that was odd, and sure enough, this guy cut right behind the cat, to steal the guts. So beware of shady exhaust guys. I think he is busting up the inners, and shop vacuuming them out for a extra payout at the scrap yard. If your a known exhaust shop guy, is a scrap yard going to think it's odd to have buckets of cat guts? Probably not.....
Good job on the video. It sounded good with both, but the flowmaster was a little louder maybe due to dual outlets. I had a thrush welded muffler on a ZR2 S10 and in my opinion it didnt sound bad on a 4.3.
Not an apples to apples comparison, since the 40 series had dual outlets. With identical pipes, they probably sound identical, being the Thrush is a copy of the 40.
Other way around...the thrush muffler has been out since 1966...I think flowmaster stole it ftom thrush...ive had both on my big block fords and i like the thrush better...
@LF X your the dufus....read what i said again...i said that thrush has been around since 66 flowmaster didnt come around for another 20 years..you little kids all think you know better
The FM is loud but the Thrush actually sounds good and is keeping it reasonably quiet.there’s a $30 difference in price.if you only want louder you could get a cheat glass pack or bullet muffler.if you want loud,,, there you go.
Very nice. Thanks for this video. I have a 1990 k1500 and been wondering what a thrush would sound like. Think I’ll stick with the flow master. Really appreciate it!
@@Moss7202 is this with factory catalytic converter(s), aftermarket or none? I’m really trying to find a balance here, I love the smell of catless systems and one less thing to worry about but also not wanting too much rasp or excessive nose. Your 40 series here is great. One other question: Is it original 40, super 40 or delta flow?
@@calebwhite1454 There is no “cat” whatsoever, I bought it in 1994 from a police officer and he had removed it and had a cherry bomb muffler behind it. The muffler that is on it now is an original 40, single in and dual out. It has just the right amount of growl
I'm looking to take the stalker exhaust off my 2000 Sierra with a 5.7 Vortech and find something that will awaken the neighbors a 5 a.m. It has dual inlets so I'm debating over dual glass-packs or a cherry bomb extreme . But those sound pretty good right there .
You made a video like you've been doing it all your life! I like your version the best ,so far. Beautiful truck by the way ...show off your engine next time. Love to see it. Keep up rthe great work. I to am sitting on the fence about Flow master 40 or welded thrush. What did you decide?
I like the Flowmaster the best. Maybe because it has two “out” pipes. It has a little more growl when you get on it. I bought the truck in 1994 slightly used from a police officer that had installed a cherry bomb muffler on it. The flowmaster beats them both in my opinion.
square guy 90 The Flowmaster 40 has a better sound from the inside of the truck. I'm not sure if that is because I have the duals coming from each side or what. It also seems to have a better "growl" that you can feel, more so than the thrush.
Ken Murdaugh I've actually ran the magnaflow rumble series exhaust from auto zone, they are s chambered muffler like a thrush or flowmaster, but I noticed on image displays of the insides, they're all different, I guess if they were all the same as flowmaster they would probably get sued over copying them
Subtle differences and yes you're right copyright laws and all. Engine h.p. output, length of pipes, diameter of pipes, whether or not you have cats, position of pipes, tips, as well as the tone of the muffler itself play a part in the sound. Oh and don't forget about the mic that you are recording it with for these videos.
Yeah as others have said nice job putting this comparison together. Well done. Now the question is did you stay with the FM or go back to a Thrush? I’d imagine the FM would be sort of loud to live with on a daily basis. Sounds good...just seems a little much to deal with etc.
I have since repainted the truck and replaced the bumpers, grille, all of the chrome and added a cowl induction hood. Because it is a short cab(standard) the muffler is behind the cab and therefore not that loud. I'm old as well as old school so I like the rumble while looking out over that hood.
Ken Murdaugh 1 day ago No Thomas, I bought the truck in 1994 when it was just a year old. The catalytic converter had been removed and a "cherry bomb"was installed when I got it. Good question.
Sounds pretty good which is weird I watched other video,s while back on this and they sounded like crap with flow masters I guess they had the camera to close or something or they just had bad equipment
I use a panasonic HC-V700 hand held little recorder. It has an EXCELLENT stereo mic on it that really pics up the sound well on live concerts, music and just general STUFF! Thanks for the "flowers"!
Flowmaster won this one-particularly due to the 2outlet style, turning it into a dual exhaust wannabe sound. For comparing exact size and setup aka apples to apples, thrush usually wins over flowmaster it seems...usually
It wasn’t that loud on my truck. My buddy just put true duels out of headers, with 2 3/4 pipes from a 5.7 with a medium cam and it’s a little much fit my taste. He loves it and that’s all that matters!
Yeah jasonneal they are close. From inside the truck the 40 has a rumble that the Thrush didn't. Changing it to coming out of both sides probably had an effect as well. I love the 40.
I wish all exhaust videos were like this great job!
Thanks GeorgiaBoy!!
The welded thrush muffler had a pretty good rumble, but the Flowmaster 40 series had a deeper exhaust note rumble, sir....excellent demo on the two mufflers
Qunice Toole thanks
I agree
So glad I saw that cuz now I'm going with flowmaster I almost wished over something said go to RUclips and watch a video or two I feel better now whoever had in town about you can get out now
The only bad thing was that both mufflers are different setups. I wish it would have been apples to apples.
Among the best quality exhaust comparison on youtube! Be proud of it sir.
Thanks Steven!
This is definitely without a doubt one of the best exhaust videos I've seen on the tube! Great job!
Thanks for the "flowers" Felix! I appreciate it!
Awesome job. Very well done, idle, starting off, drive by.............you sold a pair of thrush welded mufflers.
I agree. Compared to the 40 series it has the sound i want from a distance. They sound identical up close but from a distance the 40 series is way louder than the thrush, and im not trying to piss my neighbors off when I come home from work at 11:30 at night

I'm 45 and I hope I never grow up! I love my toys you can still be responsible and immature at same time!
LOL..I totally get it. I just went on a search for my first subwoofer. The opinions of an old guy vs. what the younger guys want simply A'INT the same!! Found one though and am quite pleased.
That thrush sounded better then i thought it would love me some old 40 series always ! Nice job.
You and me both! Thanks!
Oh very nice, both of them are great but I prefer Flowmaster. H pipe or dual straight pipes without crosspipe on it? Thank you Sr.
Me and the dog enjoyed the vid,thank you sir.
my dog loves that old truck.
I had the same truck with Thrush and loved it. People would ask me what I had. Mine had turn downs straight off the outlets of the muffler.
Both sound amazing!!
You won't be disappointed with either.
Great videos 👍
I like the American made Flowmaster's better than the Chinese produced competition.
Awesome video! That flow master does sound nice. I myself have the thrush welded on a 3.9 dakota
i have exact truck as you, except now with a engine swapped 5.9 and with carb...twin 3in thrush welded, dual exhaust
I Wish all comparison videos were this way. To the point and no mumbo jumbo from a wishful future youtube celebrity. Nice job sir!!
Thanks! i had a ball doing it, while upgrading my old truck in the process!
Awesome job on the video. Thank you for the effort you put into it!
Thanks

angus42868 thanks, god luck and let me know!
Exactly what i was looking for! and same engine as me. I went with the Flowmaster simply because of availability but i would have preferred the thrush so i could sport that woodpecker sticker.
Hard to beat a woodpecker sticker!!
This is exactly how a comparison video should be. Damn near side by side comparison, no chit chat in between. I personally want to hear the products in hopes of making an informed purchase, not a bunch of talking in between.
Thanks! If I would have gotten to running my mouth it probably would’ve drowned out the mufflers!! Thanks again.

Well, sir. You have helped me decide what to do to my 90 cheyenne.
I'm going the thrush route. The flowmaster has a tinny sound to it.
I don't know cavalier, seems a bit "throatier" to me.
Great video and comparison
Great video sir I loved it. I have a 95 5.7 and now that just made my decision even harder lol. Both sound great!
The change from the "one out" to the "two out" made a significant sound change to me.
Honestly, not a whole lot of difference in sound. Probably the real question is, what do you want to pay for? One is aluminized steel the Thrush , and the Flowmaster I think is stainless.

I think a cam lob jacked up on me or something so pulled it and threw in a doner that runs good enough.
Seems like it had a little more UUMMPH in it after I installed it. Broke the crank just after it was in paint shop.

True Muznick, also the Thrush was routed out in front of the tire, and the Flowmaster was routed out of each side.

Had a thrush on a 97f150 years ago. I thought it sounded great. Thrush 17649 welded I think was the number
Very nice. Thanks for this video. I have a 1990 k1500 and been wondering what a thrush would sound like. Think I’ll stick with the flow master.
Really appreciate it!
Nice! That was my choice and I’ve m vet looked back!!
The 40, 1 in 2 out sounds sweeter! Great video!
I think so too!
THANKS!
@@Moss7202 is this with factory catalytic converter(s), aftermarket or none?

I have flow master 40 on my 91 love the sound
Yessir...hard to beat.

nd yes I know, I should kick my own ass for getting rid of them.
Flow master for sure.
I'm a fan for sure.
Awesome video even though it's 3 years old just help me make my decision I will be ordering thrush for my International 200 today👍
Glad I could help
Thanks for a great video. Wish they were all like this
Thanks Jadan
Thank you! Great video!
That’s a gorgeous truck 🔥
Thanks! I've since had it repainted and interior redone. Love it!!
I can tell the difference! Flowmaster is the right choice!!!
On the Thrush did u have single in and single out or dual out? And also is the Thrush just under the truck and pipe(s) coming out or what?
It was a single in and single out with a pipe coming out of the passenger side, just in front of the rear tire.
Great comparison video sir!

No cat. Was deleted when I bought the truck.
both have similar design features, and similar sounds, only difference was your thrush didn't have a tail pipe

RUclips video editing score: 1000%. Perfect comparisons. Was that an original 40 or delta/super?
ChillCosmos original 40
original 40 and thanks for the flowers!
Does your truck have a catalytic converter......that would also change the sound with the flowmaster 40.

1 day ago
No Thomas, I bought the truck in 1994 when it was just a year old. The catalytic converter had been removed and a "cherry bomb"was installed when I got it. Good question.
I t does not. I bought the truck in 1994 and it had previously(1year) been owned by a police officer. It was "catless" when I bought it.
Isnt thrush welded a knockoff of the 40 series?
For singal exhaust flow master but both sound great Can't make a electric car sound like that lol
It might take a litle more effort, but keep trying!!Haha
Sounds pretty good which is weird I watched other video,s while back on this and they sounded like crap with flow masters I guess they had the camera to close or something or they just had bad equipment

Ya gotta tell me which one!!??!LOL
Ken Murdaugh I’m going with the Thrush which sounds just as good!
Thanks for the video and nice ride!
It's now repainted
Thanks Ken!
You're welcome!
Nice thanks!
What a great video! Great side by side editing. 5 stars!
Thank you sir!!
Great video, sir! Make more!
Thanks randomnumber81!!
I've used thrush all my life before there was all those other brands just old school I guess
Flowmaster won this one-particularly due to the 2outlet style, turning it into a dual exhaust wannabe sound. For comparing exact size and setup aka apples to apples, thrush usually wins over flowmaster it seems...usually
Nice video!!!!!!!!!!
Thanks!
All I have to say is that you had tailpipe on flow master and none on thrush. I had both on my 97 and both sung could hear my for blocks
My Jack Russell Terrier (which has supersonic hearing, by the way) can hear me coming for 5 minutes before I get home!!
Put a thrush welded on my 5.7 tbi with a hollowed cat it’s way too quiet
It wasn’t that loud on my truck. My buddy just put true duels out of headers, with 2 3/4 pipes from a 5.7 with a medium cam and it’s a little much fit my taste. He loves it and that’s all that matters!
awesome job!
Thanks Brian.
They sound so close to each other
Yeah jasonneal they are close. From inside the truck the 40 has a rumble that the Thrush didn't. Changing it to coming out of both sides probably had an effect as well. I love the 40.
Great vidieo
Glad you enjoyed it
Thanks!...
Flowmaster
Agree
THRUSH WITH TURN DOWNS TURN HEADS AND PUTS SMILES ON TRUCK OWNERS
Yup!
Thrush
40 seems smoother but it may be due to the install being a whole lot better.
sound the same to me
lose..but the Flowmaster is a little lower.
Very close, but I think that the flowmaster sounds a bit louder and lot smoother but it may be due to the better install and tips.
