Guys, I want to know how it looks like, from the headers back...Does anyone know if the headers bolt on to the ypipe, or if it is one piece strait to the cat...thanks....3.5L remember

The headers bolt to the Y- pipe, which bolts to the cat. The cat is then bolted to the b-pipe and finally the rear section.

amazing....so then why are they not more ypipes for the 3.5L...also, to add, the bpipe then bolts to the muffler.

Nope. Headers replace the Y pipe as well. The headers include the Y pipe.Originally posted by CBass69187
