Re: “Quiet” performance mufflers

I just ordered a set of Walker Ultra-flow welded for my truck. Interesting that the old ones failed right after this thread started...

Were the old ones Walker?

I believe the old ones were Hooker Competition mufflers. Standard mild steel case, rolled seams, nothing special. I can dig out the receipt if you're curious.

I've used Walker Ultra Flow on a few projects before. In a turbocharged four cylinder application they turn what is usually a buzzy or raspy sound that I think sounds like a cow with a nasal condition into a note with a distinct low frequency component. I'm all about the base...

It will be interesting to see how the '57 sounds. 302 cubes, 9:1 compression, and mild cam means it's not a screamer anyway. It was pretty mellow with the old mufflers.

Re: “Quiet” performance mufflers

I used a 50 Series Flowmaster that was an SUv muffler. My exhaust on my 48 exited just in front of the rear wheels. With it being a short system, I didn't want it loud. It was a nice sounding system. 2.5" SS pipe with an H pipe.

I also found this interesting sound chart for Flowmasters.

If you like, DM me your email I can send you a video clip of the 50 series at idle.

Re: “Quiet” performance mufflers

I've been running the same exhaust setup and muffler with my TPi 305 and now a stock 5.3L LS. Basically 2.5 inch pipes off the headers, to a 18" body magnaflow muffler, 3" single out that exits behind the rear tire past the body. It's got great sound on the outside but zero resonance in the cab. Very nice to drive.
