Contour Enthusiasts Group Archives Forums Modifications Duratec Performance MSDS Headers and Y-pipe...performance?

mikey - there was a guy who dyno'd w/ the MSDS headers and the SHOShop pipe, then with the MSDS pipe and the MSDS pipe had a few hp on the SHO pipe. Theory is that the bend in there is for extra hp...the stock pipe is just ugly on the inside.
