Check out the latest quality performance piece by Alphawerks. This Lexus IS300 header is manufactured to the strict ISO-9002 certification standards made of T-304 true stainless steel and polished to a mirror show finish. The header comes with all gaskets, collector pipe, high flow cat, and a stamp on every exhaust piece to ensure authenticity. Most importantly, this header lays down 14bhp and 15 ft/lbs of torque to the wheels with the stock exhaust and stock intake. These are true bhp numbers. Alphawerks does not dyno cheat by doing the baseline run with the a/c on full blast to show lower baseline numbers like many competitors do. Best of all, the header is a perfect fit. The kit is engineered to be easily dropped in from the top of the engine bay with ease.
