cummins_power said:4" with a flow-through muffler or strait pipe is plenty. 5" is noise and people really moving a lot of air. You should already have the hx35 on your rig. You could go to a 14 or 16 cm exhaust housing, but again more lag and you proble don't need it.
You don't get one for an hy. Wow, thats crazy, I didn't know that any ever came on a 2000. Yes, an hx would make a big difference for you then and cost a lot less than an s300. If you're interested, I have one sitting on the self, shoot me a pm if you want.Onebadtruck said:where do you find a 14 or 16 cm exhaust housing?
