With the great success of our original Swap header, we have decided to add another option to our header line up. This stainless steel header is a 4-1 Race design with a true slip-fit merge collector for maximum exhaust flow. The Race header is designed to deliver power gains in the upper RPM range, making it perfect for drag racing and street use. Like our other headers, it fits perfectly under shifter mounting kits and is well centered in the exhaust tunnel. The flex-pipe absorbs engine movement, and the optional flange allows installation to existing exhaust piping with minimal modification. Please note that all of our headers will require some exhaust welding for installation.
