Just a FYI for anyone thinking of the Pypes O/R X pipe there may be a problem with the latest batch. Went to install my Pipes O/R X today just to find out that the upper pass side O2 bung was welded in the wrong position. The O2 sensor hits the starter preventing proper alignment of pipe to manifold. Dropping the Pypes pipe down and laying it next to the stock H I could see that the positioning of the O2 bungs were off. The only critical O2 angle is the upper pass side only because the starter is so close but unfortunately that's enough. Also, the bend on the pass side pipe is off somewhat too so even if the bung were OK it still would not have fit and/or sealed well against the manifold. I've notified the vendor.

 

That sucks Ron..... hopefully they get it fixed and you get'r done soon.
