[bigblockcoupe]

once again if you retain the factory converters it is very quiet but when you put on an h-pipe you no longer have converters therefore the exhaust is louder but personally i don't think it's that loud i have the american thunder cat back with dumps an h-pipe and full length headers on my cobra and my coupe and both are modified with cams, heads, intakes,etc... and the cobra is supercharged and i think they are not too loud but everyone has their own opinion i can carry on a conversation just fine in either car.
