Seems easy enough. Walker exhaust pipe was much cheaper here then at a local auto parts store. Exhaust pipe ships free, but the 3 exhaust gaskets I need to not. I chose to buy those local and not have to pay $11.50 in shipping. Prices for gaskets was are about the same local or via autoplicity. Gaskets $13.98 vs local $15.27
