I picked up a slightly used cheap UPR catted X pipe for my '02 GT. When I search the forums, I read that there is a small extension (?) and a metal gasket (for the passenger side exhaust manifold) that is supposed to be used to not have any leaks. When it arrived I got the 2 pieces of the X and a small 2" or so extension but I see no metal gasket. Are the threads I read correct that there are supposed to be these 2 additional pieces (extension and gasket) and what is the gasket? Can I pick one up at Advance or a muffler shop and lastly, what he hell is the little 2" extension for (or is that the "gasket"). Ugh, I wanted to finish this over the weekend.
