if you live in the U.S. you have to have a cat on that car.. go to the cherry bomb website and look around they carry not only the original glass packs but also low flow mufflers..

the loudest muffler i know of would be a glass pack but a car like that is not suppose to be loud ! also without a cat you won,t get it inspected !

Go "greddy" they never disappoint.

I have a greddy dual exhaust and i love the sound.

Why would you want a louder 6 cylinder? You must be a real fart smeller, I mean smart feller.....

I have a 2001 Pontiac Grand Prix and i have no cat or resonator and i was just wondering what would be the best sounding muffler i could get welded on. I dont want it straight piped. But im looking for the muffler with the loudest possible tone.
