How much hp increase with headers and catted x pipe?
2010 C6 1LT, MN6. 9000 miles. So far I have a Z06 intake horn, 160* T-stat, tune and Borla Touring axle back exhaust for 380 hp & 6100 rpm at rear wheels, 377 lb. ft. & 4400 rpm at rear wheels.
I'm going to add Kooks long tube headers and catted X pipe and a re-tune and wonder if the headers and X pipe will get it over 400 hp at the rear wheels.

I picked up 22 both rwhp and tq, above a already tuned only ls3. 47 rwhp total from stock, with tune and headers catted, corsa 160 stat and vararam.
I lost 7 rwhp going to the ZO6 set up with the stock air box back in. More so with the Tq power.

No, the hp loss was going from headers catted to the Z06 Manifold and cats with H pipe system and back to the stock air box. I believe the tune was more conservative also with the Z06 set up.
