I'm in the process right now. I'll post pics as I progress. I just recived it today. The 4" pipe is a nice piece, but I will have to do some surgery on it I think. I am also modding the intercooler plumbing for the Precision front mount. I just finished bulding a 3.5" OVAL down pipe for it, so I wanted to improve the intercooler plumbing while I was at it. It use to use special 3" close radius nitrile elbows (Turbonetics pieces), but they would pop off at high boost. I am building 3.5" oval inlets to gain some ground clearance. The car has been lowered and every .5" is needed. I took some 2.5" cast aluminum elbows and cut then along the lateral center line and then welded a 1.25" strap into them. They are now oval and welded to the intercooler inlets. I still have to add a few inches to get them past the radiator core support. I'll post pics soon.
