So, I bought some headers from Mac Performance Tuesday. Installing them tomorrow morning. Anybody know what kinda HP i should be getting from these? we are taking off the cats and using the off road y pipe that came with the headers. I'll post a video tomorrow of how it sounds, if it sounds any different.

You'll feel a nice kick in the ol' butt dyno. It will pull alot better in the top end, that's for sure. I did mine earlier this year.

i would say with lt's and y pipe ur putting on around 340rwhp. could be more but i would say 340-350 at the wheels is a safe estimate. if u would get a more flow freeing cat back instead of the flowmaster u might pick a lot more. maybe enough to push u over the 350 mark
