Hey guys looking to retire my 72 el camino and bring out my 66 chevelle this season. I'm getting ready to do an exhaust system and wanted to konw if there is a muffler of choice that everyone is using.

Dyno Max Ultra Flow and Pypes Welded Race Muffler. I prefer the Pypes Race

None of you guys use Magnaflows?

I don't know.

I think that is what I will end up using on my cars. A good friend of mine went from a 3" system dumped at the axle with flowsmashers to a 2.5 Magnaflow system with tail pipes. It picked up around .2 and quieted it down a lot. I've been a believer since then. This is on a high compression 383 SBC with a healthy shot of dope, runs bottom 10s - all steel, full interior and a baby seat.

With that said, never heard anything bad about the ultra flows or the pypes mufflers.

I have the pypes stainless oval welded, picked up a good bit,lozst the 2000 rpm drone I had. I got the one step from the loudest. Car is quiet enough. They are just like the ultr flows

I have dyno max ultra flows on the Polara,and Flow Master 3 chamber mufflers on the Super Bee

Pypes Race Pro on the Camaro.

Borla's
2.5 w/ H pipe!

My car has Pypes Street Pros on it. I didnt like them at first. They were a bit to quite for me but they have grown on me. However they are fully welded and dont looks stock.

100% legal and may become the official muffler of the SuperCars series in the future. The only Pypes muffler not 100% legal is the Violator . Stay away from them if you can, they are way to loud and don't work on these cars.

Good to know, Thanks.

I run the Violators on the chevelle, they do pass the 107 db spec., but, have been told they are alittle loud . Anyway, to stay with-in the guidelines may change in the future

I ran 3" 2 chambered flowmaster on my last 3 cars so I was a little shocked how quite this thing is. Of coarse its only 200hp and still has the 1-7/8" pipes off the manifolds right now so that isnt making it any louder.

pypes race pro, one step up from violators, quiet enough.
