Hi guys! I just bought what was listed as a stock x-pipe takeoff from a 2003 Saleen S281 s/c from a guy on ebay. From the pictures, it looks like a Magnaflow x-pipe with stock looking cats. Does anybody know who manufactured the mid-pipe on those cars? And do you think I can get a slight performance bump installing it on my 03 Mach 1 which has a Borla stinger cat back and a stock h-pipe? Thanks for any info you can give me.
