I just bought a semi-used CorkSport race pipe. I didn't get any instructions with it, but I found a pretty detailed how-to on another Mazda forum for the TurboXS race pipe. All that was included were two pretty big bolts and two washers. In the pictures that this guy put up for the how-to, it shows not only the two bolts and two washers that I have, but also two smaller bolts and washers, a total flange gasket, and a circle flange gasket. Do I need the gaskets that are shown with the XS race pipe, or can I get away without them (maybe the CS test pipe is different)? Does the CS pipe include instructions? I didn't see much on their website. Let me know what you guys think.
