Mac Headers
Hey. Just wandering if anyone here has used mac mid length headers on an LT1. I would just go with long tubes but I am not really sure of my emissions requirements, so I was looking at these. Mac's site says something like up to 28 extra hp to the wheels over the stock manifolds. If you have any opinions, let me know.

RE: Mac Headers
you can go with longtubes and pass emissions, but you will have to make a technically "illegal" modification and move or replace your stock cat. I'm actually in the process of doing this now(LT headers and Y pipe are on the way in the mail). As far as the Mac headers go, I have not really read much about them, but I doubt the 28 wheel HP over the stock manifolds.
