i have a bbk o/r h-pipe and american thunder cat back, the drown gets anoying sometime but its pritty loud. also dont put dumps on it, that does not make it louder it just seams louder becuse the exhaust is right under the car, and then you have all the exhaust fumes in the car.

I would go with glasspacks, they are loud and cheap.

A little break down......................

Flowmaster = to high at idle

SLP = you need to own a GM

Borla = not loud enough

Mac = loud and mean


Personally go with mac...

Tims 88GT

you dont have to own a GM to have slp! i agree that mac sounds good but i like the slp better. way better sounding than the flowmaster 40's i had.

i have flowtech o/r h with 2.5" flowmaster super40's. not really loud at idle but man is it a monster at WOT. i still wish it was louder. neone have ne suggestions for mufflers?? the super 40's are loud but have a weird rattling sound. my friend says he cant hear the rattling from outside the car but its really noticeble from the inside
