Is a tune necessary with install of LT headers on these cars with cats still installed??

Yeah, even with the high flow cats you'll set a light for the rear o2's plus the tune will usually get you another 10+ rwhp.

OK, good info. I love the extra power but what I really want is more mileage on the highway, so if I can install a nice flowing exhaust and LT's and high flow cats, Id like to get a tune done with keeping my mileage up as best as possible.

is the x pipe included ?

is the x pipe included ?

Yes, the arh system goes all the way back to the muffler flanges. If you have aftermarket mufflers without the flange I can have them make the pipe into a slip fit rather than flanged.

what kind of gains are usually seen with this set up?

Headers,CAI, dyno tune usually see 60 hp gain at the wheels

The numbers posted above are about right, with just the headers and tune you'll probably see 40-45.
