vrburt 0 Posted March 22, 2009 Report Share Posted March 22, 2009 As above. I have a exhaust system to fit next month and it came with a de cat pipe. But im really not sure whether to lose the cat or not. If i do remove the cat does that that mean a re map ?? As i've heard you can get quite nasty flat spots in the rev range. Would i be better off getting a sports cat ? and does that involve a re map ? Or just leave the orignal on there ? :^) Any help on this would be greatly appreciated as im a little out of my depth here. Link to post Share on other sites
