The previous owner installed a bbk h-pipe from AmericanMuscle and kept the stock manifold. The car has an exhaust leak where the manifold meets the h-pipe on the passenger side. I took it to an exhaust shop and the owner told me that I would either need to find a gasket that's thicker and better quality than OEM (option A) or (option b) get some headers. AmericanMuscle says that the BBK h-pipe is meant to go with bbk long tubes and I'm guessing this is why... Does anyone know where I can find a thicker/better quality gasket that would go in between the manifold and the h-pipe?
