This header delivers the best peak horsepower gains while utilizing a 3-piece design. Recommended for high liter (2.4 to 2.5+ liter) K-Series engine swaps.
The header comes with 2 exhaust outlet pipings, connection by v-band flanges, for you to custom setup your own ideal hood exit or fender exit header. Due to different car setups, you may need to extend/trim the exhaust piping for ideal fitment.
