Apex'i Muffler

Whats louder, the apexi n1 n/a muffler or the n1 turbo muffler?????

n/a. exhaust streams don't exit fast enough and cause more droning with in the piping. Thats why they sould like a continous fart. Turbo cars sent air streams out alot quicker, thats why ours sound lime S-B-D's.;)

Thanks dude:D
