How do I make my 454 quiet?

They claim its the same flow as the super turbo's just quieter.

Walker = Dynomax. Same company.


Its the last one they try on this video.

Generally, the longer the muffler, the quieter it will be.

dynomax walker offers the quietest performance muffler according to about 2 minutes of research. to find a muffler that's quiet and doesnt add any power...ehhh thats gonna be hard imo,not impossible but, probably a pretty moderate search. hope that helps posted a link below

I have the Dynomax Super Turbos on several cars and they do sound nice, but not stock car quiet. When I had a Pontiac 400 in my Malibu wagon I thought if I put a stock type replacement Walker on each side of true duals it would be super quiet yet flow great. Well they did flow great, but were not quiet all all! Conversely, I used a single Super Turbo on the same motor but as a single pipe exhaust and it was quiet! I'm still mystified by that. Some thing to do with the resonance of 4 cylinders vs 8 cylinders. On my current 301 wagon I ended up using the biggest size single pipe Walker replacement system Rock Auto offered, '78 ElCamino 350 I think, and it is very quiet.

Walker Dynomax Super Turbo mufflers are some of the best at keeping big cubes quiet yet still have a nice mellow tone.. I had them on my Pontiac ported 462 and they were too quiet.. I ended up with long 6" round Magna Flow packs...

A Crossover pipe made my car louder, the X pipe will make it sound like a V-6, in my opinion...

Walker/DynoMax Hemi Super Turbo mufflers.

They also make them for motorhome/RV even quieter.

Best, highest flowing turbo muffler is the DynoMax Super Turbo.....deep mellow sound...

I have these on my Lincoln and they sound great with a nice mellow sound, I didn't want anything loud but wanted something better flowing than stock.
