Thread: Dynomax Cat Back

I found a Dynomax Super Turbo Cat Back Exhaust System for my 2001 Pontiac Grand Prix GT. It's $414 with a $75 dollar rebate? Does anyone have this system on their car? If so, how does it sound? Thanks.

Its cheaper on RockAuto IIRC.
It sounds pretty good.

It was on the Wife's car lol but again it's sounds decent.

Very true.

Within a year and a half, both mufflers rusted out badly. Maybe because of the salty New England winters and the fact that it's aluminized. The rest of the exhaust was in good shape. The mufflers do have limited lifetime but that's a one time replacement. Kinda pathetic.
