i know i should really get the standard bolt on trd, fireball, kazuma, or one of the other ones out there, i wanted to do something different and see what happened, so i had a pipe made to fit from the stock bolt on, and wound around to end at an aftermarket muffler, it sounds pretty nice and it gives a noticable power increase, but i was just wondering if it would be worth gettin something like a trd exhaust or whatnot
