I've got a 97 mustang gt that the previous owner chopped the whole exhaust off, so it drones incredibly bad and doesn't sound very good. I just got a set of hedman long tubes and was gonna buy a flowtech x pipe but don't know if it actually will bolt on my headers. I want the exhaust to be routed the right way and use the factory hangers. Will a catback like the pypes violator fit in the factory spots?
