hey i have a 1999 mustang gt completely stock except for a couple of flowmaster mufflers. i was planning on buying some headers but i wanted to know if i would be better with long or short tube. also i wanted to know what sounds better, x or h pipe?
hands down go with long tubes...you'll be pissed if you go through all the troubles og getting shorties in there and not even feeling a difference and realizin you only gained 2hp
as for the mid pipes, just like vee eight said, h's give a low rumble, x's have a high raspy sound..keep in mind though, flows sound like total ass with an x pipe... check youtube for exhaust vids
