I apologize for the lack of clarity, but my question was directed more towards will an aftermarket x-pipe bolt up the the pacesetters. I am planning on doing a high flow cat setup at the same time, and was not sure if I should just have a shop do some custom work or look for a prebent setup
Are you running stock exhaust? If so, get the pacesetters and the slip-on flange connectors. They will allow the headers to bolt up to stock exhaust. Then get a universal x-pipe and swap it in place of the resonator (do a search on here and you will probably find a few options). If you want to run cats, you can grab a couple high flow cats and weld them in wherever you want...probably between the headers and x-pipe.
