It depends on you. If you're welding on, the tip has to be at least bigger than your current exhaust pipe (I believe stock is 2 1/4"?). But there what it has to be is that the small end of the tip is just bigger than your exhaust pipe. If you're going screw on, well, basically just find a tip that has the screws long enough to attach themselves well to the exhaust pipe. In this case you might want to find a tip that's also long enough to cover the old pipe, otherwise it's gonna look ghetto. Also remember your rear bumper... Get a tip too big, and you're gonna be looking at cutting your bumper (which is fine if you do it right). __________________ 1996 Hellrot 318ti - RIP |
