Fabricating a downpipe for a 00 Civic Si....???
Hey guys, Ill be goin boost in about 2 weeks with a kit that I have been peicing together for a couple weeks now. I have a 2000 Civic Si, and my question is, Im fabricating my own downpipe and am wondering how many O2 bungs I will need, and if its only one, what end do i need to weld it on to? Is it up near the top closest to the block, or down near the cat? Any info on this would be appreciatted, thanks guys
