Has anyone used them? My relatively stock 350 Chevy powered 1930 DeSoto had Magaflows on it when I bought it...very loud. I replaced them with Walker turbo mufflers but it's still too loud. I considered stock mufflers but a shop suggested resonators mounted before the turbo mufflers. I know nothing about them. Will they reduce exhaust noise? What can I expect in the area of noise reduction? I don't mind a light rumble but I don't want to alarm the neighbors every time I fire up the beast!

I have Walker Quiet-Flow mufflers on the 49 with the 4.8. Haven't had it out on the road yet, but at an idle & reving up, very pleasant, nice little rumble, not raspy. I hate the sound of magnaflow & flowmasters.

On my 51 Belair, sbc, unknown round mufflers, had an annoying "growl" at certain speeds, installed an H pipe crossover before the mufflers, helped a lot.

I put Brockman's on my 6 cyl dual exh, if you call them tell them the sound you want they will built to your want's. Cant hurt to give em a call. I am very happy with mine.

I've had two V8 cars with resonators. My tweaked '96 Caprice (Impala wanna be) had Walker Quiet Flow mufflers and factory resonators on the rear. I removed the resonators and there was no increase in interior noise. The Walker Quiet Flows look and fit like stock mufflers but flow much better.

My second car is a '69 El Camino SS-396 with 2.5" stainless pipes, Edelbrock cam, intake manifold, and carb and MagnaFlo mufflers. It was unpleasantly loud inside the cab. I added an X-pipe and 12" resonators at the rear of the pipes and the sound is sweet! It sounds similar to a V12.

How exhaust sounds is extremely subjective and you have to rely on your own ears. Be somewhat skeptical of what others say and judge for yourself.

Good luck with yours!

Thank you for your information. The shop I'm working with is suggesting I put the resonators before the mufflers. Wondering what that will do?

Interesting they would say that, I wonder what their reasoning is for that. I've always seen the resonators on the very end of the exhaust system. The old mid 60's T Birds, Impalas and the like all had them at the end.

Me too, but I'm thinking there's more room there to put them.

Just as it really is info:

Resonators are just that, they dampen resonant frequencies in the exhaust systems.

These frequencies are not like radio RF, but are pulses in sound waves that distort exhaust flow, and cause problems in the clear, clean, smooth exhaust gas flow.

They usually have nothing to so with noise, only the frequency distortions in the flow at various RPM's.
