on a small displacement N/A enginetest pipes sound like a fart out of a loose ass hole
yes but that is from inside the car. totally different when driving behind someone, you can easily tell if it is a test pipe or not.honestly i i say either or...but i dont know where you guys get the loud raspy, loose asshole fart soud from because i run a 4-1 header, testpipe-------2.25 piping straight through a es oval muffler which is also 2.25 in & out. my car sounds nothing like what ya'll say ohh well
