    What kind of CAT.?

    Just wanted to ask you guys where you got your catalytic converters at, and what price is reasonable them? Also, what are your opinions on the RK Sport headers for the 3.8? I seen alot of people with bad experiences with them leaking.

    500 bucks for RK sport headers IMO are a of money for 5 or so Hp. Wait to pacesetter comes out with theirs for half the price. As far as the cat converter, click the catco link in my sig.

              No... the outlet on your Y-pipe is 3".

              The collectors on the manifolds themselves are smaller... something like 2" or 2.25" I think?

                RK sport headers: cut the 2 bolt flanges off and either have a 3 bolt flange welded to it or weld it directly to the y pipe
