smiddy 76 Report post Posted April 20, 2009 Hi Guys, been working on this for a while, has been difficult to design. Short Header to bolt direct to OEM front pipe. Top end power is around same as OEM manifold, but according to car owner part throttle and mid range power and torque gains are there. Currently re-designing runners for longer length. As pics show there is ample room for mods. Quote Share this post Link to post Share on other sites
