quiet mufflers

[Doober]

Cruising I don't really have any resonance with the Pypes system, but if I'm on the gas at all it gets quite loud Nice deep rumble at idle too, I think part of that may be due to the rotted out quarter panels letting sound in, then it resonating in the trunk.

ok i think i have determined hat sound i want...i want that quiet tinny sound..i have heard a few at the track but never paid attention to what mufflers they had..i did watch a u-tube vid with a g-body that had that sound, but cant seem to remember where the link was??

Resonance will probably increase, it almost always does, though it varies on application. The heat cycling of the mufflers/pipes tends to harden them so they don't do as well of a job. Every system I've had or had done always gets a little louder over time.

yea, almost all these turbo style mufflers have a glass -type packing..that burns out of course..lol..if they would only stay like they are now ...

The "Welded Thrush" mufflers are not Flowmaster knock offs! If they were then why do the W/T flow more/better and sound better with less resonance? Did Thrush make improvements? Flowmasters are some of the worst flowing mufflers you can buy. Dynomax "Ultraflows" are some of the best flowing mufflers made but paying $85.00-$105.00 each kinda sucks.

On a budget it's really hard to beat the Welded Thrush mufflers. If you want a quiet system you would install expansion chambers or what the factory called resonators prior to the muffler. I plan on fabbing up a set of boxed expansion chambers for mine to maintain free flow but stop the noise. JD

ok update the long hush thrush turbo muffs sound awsome on my malibu dumping before the rear axle,....buuuuttttt those same muffs on my 72 wagon sound terrible!!.. they are run behind rear axle and out..i cant stand the sound under light throttle..idle good , taking off normally sounds bad..really bad..wide open sounds good..this car has manifolds not headers..i'm considering having them replaced and i just got it back!!..argh!

I read that article a long time ago & I'm doing a very similar system when the time comes.
