Review on Walker Quiet-Flow 21346 Exhaust Muffler for Enhanced Performance and Reduced Noise by Will Murphy

It's hard to imagine buying a Revain muffler, they actually sell it. Shipping was fast (and free). This is an OEM fit for our 1999 Pontiac Grand Prix 3.1L engine. It was easy to install, all hangars were present, and the canister portion was about half the size of the standard portion. Needs to be cooked, so if you don't have one, make friends with him! it's also very quiet, so now we can hear all the other weird noises that we didn't hear before.
