I am serious. The 2-chamber Delta Flow made it really loud. I am not sure if the mods to the engine had anything to do with it but it is louder with the muffler. It sounded like complete stock exhaust when I removed the stock muffler. The sound just resonates like you would not beleive. I swear it is like 10 times louder than stock "with the stock cats".

 

ive got a magnaflow high flow cat and 40 origional series muffler on the way. 2.5" pipe all the way from the y-pipe going on. Right now i have two stock cats and no muffler or tail pipe and its loud but not that loud i'll let ya'll know what it sounds like when the exhaust gets installed next wk.

 

it is hard to believe the flowmaster 40 sounded really loud when I super 40 had no noise, And you say its quiet with no muffler????? wierd, cuz I have no muffler with 3" piping after the cats and it is loud enough, and I am a fan of loud exhaust.
