Muffler Shootout: Thrush Welded vs Flowtech Raptor vs Rumble Performance O'Rileys (1968 Pontiac)

In this video we go through another series of the cheap muffler shootout.
Contestants this round
Thrush Welded Muffler
Flowtech Raptor Turbo Muffler
Rumple Performance 2 chamber O'Rileys Muffler
No muffler-Straight Pipes
The drone level in the video vs real life is not an accurate comparison. You can hear where the drone comes in though. I can post a video of just the thrush welded driving around if you would like to hear that.
My Conclusion thus far. The Rumble has a mellower tone than the thrush, but it is deeper. Not as harsh in the mid range. I dont like the turbo as I said, but in this case this Flowtech had about the same drone as the Welded Flowmaster type mufflers, which was by far unacceptable for trying to quiet the car down, and achieving no better cabin noise. The rumble I still have to drive more but sounds closer to my all time favorites the Flowmaster Super 44 mufflers. The difference is I would say its a little more mellow, and has much less drone than the Super 44 would have. I recommend watching the shootout on engine masters as well. Very interesting results. I believe the sound change is due to the removal of the vents in the delta plates in the middle of the muffler, which I definite like. Good compromise for the sound I love. Car is 1968 Pontiac Catalina with a small cam otherwise stock 400. Highway gears.

I love how happy you got when you went to the parts store

Hoping we will get more videos soon. Very interesting to watch you taking good care of that beauty!

[@jasonglasmann3734]

Thanks Andrew! I went through the same thing with my f150. I saw your post and out of exhaustion and fucking tears I threw on the rumble. Holy Shit! Mature, deep, usable tone. Thanks dude! Literally giggling while driving to and from work.......

[@coyote102076]

I sold several of those, always positive feedback.

That beauty has more STEEL on both bumpers than there is in an entirely new car today. 💪💯

R22541 Rumble $55 plus taxes/free shipping on Amazon, $60 plus taxes at Oreilly's. The muffler is manufactured by Magnaflow.

I sincerely have to say this is a GEM well preserved and reminds me of the 1973 movie Shaft in Africa where his princess drove and met him in a 1968 PONTIAC CATALINA by the desert corn field which is of a Olive green and white top color.

04 Crown Vic with SCT tune, x pipe, twin Rumbles, and 3 inch turndowns. Love the Rumbles and the fact they are cheap OG FLOWMASTER 40 clones.

That reminds me of Dad's old 66 Pontiac Catalina his was white top white body white interior and his also had the fender skirts

[@erikturner5073]

The flowmaster 50 series DELTA FLOW, are the mufflers to get if you want that sound without the inside drone. They are my go to mufflers for my street car. Sound really good on the outside without being obnoxious(still turn heads). When you roll up the windows you can listen to your tunes and or have a conversation no prob.

[@ramrunnergarage5941]

It's been about a year since you installed the rumble muffler, how are they holding up? I have pair of turbo mufflers and had a terrible drone.

[@andrewschmitz6367]

Bigger diameter piping is a good way to get a deeper tone

[@Smittyschannel]

WHY did you cut off the thrush mufflers so close? Now you'll have a hard time reusing them on another car, or being able to sell them. Cut at the exhaust pipe, not the muffler

[@BigStuism]

Glasspacks are my favorite, ive spent 1000s on exhausts over the years and i always end up w glass packs in the end lol

[@jonathanvazquez9685]

Cool video man! Which are louder super 44s or thrush welded? I'm looking for louder inside and out. I prefer a crisp tone instead of a deep and smooth sound.

[@16abind]

Thrush are probably better. Super 44s though have the deep amazing sound I prefer. 100% the super 44s over thrush for me but that's just my preference

What is the part number on the rumble

[@matthewgraham2241]

What are you running on it now? Have you tried super 40s ?

[@16abind]

Haven't had the car for a year now. But I had the magnaflow on it. 40s are ok but I prefer the deeper sound. All time favorite mufflers are super 44s

[@MoparMan-ff8fb]

cut a hole on top of the exhaust pipe 5 to 7" s in front of each muffler then install a section of pipe 12"s long in the shape of an L or slight J shape and cap the other end of the pipe it will kill the drone sound

[@16abind]

I'll have to remember that for next time. Thanks

[@jasoncosgriff6742]

You can double the mufflers as in 2 on each side

[@josephknopf8590]

The exhaust sounds great and i'm guessing by how quiet the exhaust is the engine still has the stock exhaust manifolds.-

Don't remember. Try 17655

@@16abind what is the rest of the system with the Rumble mufflers? Crossover? Headers or manifolds? If headers, what brand and style?

[@timjohnson2188]

I personally love the drone

[@johng2779]

Just take the mufflers right off and run straight pipes. You won't ever find a muffler to come close and you won't be disappointed at all. Specially with those big Pontiac engines. For serious.

[@johnandersonjjr]

Best thing to do is build a time machine and go back in time and buy a factory type system.This is necessary because the muffler makers refuse to make the 3tube reverse flow deals they made back then(just too loud 2 tube el cheapos)

Ture dual exhaust is always quieter than one muffler

H pipe or X pipe fixes that. X pipe sounds the best but H pipe would probably take more drone out than the X.

[@ryancalhoun4671]

X pipe takes out way more drone

[@shanew.williams]

I respectfully disagree. I am the owner of a Dodge Coronet with a 440 big block. I too tried the "Rumbler" mufflers (Autozone). It was loud. About as loud as your Pontiac when you were first cruising with windows down. An old timer once told me the two hardest engines to quiet down were the big block Pontiacs & Mopars. I suspect you're experiencing less of the annoying loud "Waaa!" sound of the Rumblers because your Catalina has excellent sound deadening in passenger compartment compared to my old Dodge.

[@mikehall737]

I would take the old muffler off your hands lol
