What kind of performance improvments have you guys with Flowmasters seen? I'm thinking about a 2.5" in/out Super 70 for my XJ and have been told Flowmasters don't "flow".
i have pacesetter mid-length headers, no cats custom 3in y-pipe with a 40 series flowmaster dumped down. its loud inside of the truck and WAY to raspy. so i ordered a magnaflow and running the exhaust out the back, like the 2010's and up do.
