alan83 Posted January 17, 2006 Share Posted January 17, 2006 I have a uk tt and it still has the original full system. I am considering taking the cats off, will this increase or decrease fuel consumption?. Or am I better to get a new de cat exhaust?. Link to comment Share on other sites More sharing options...
Ian W Posted January 17, 2006 Share Posted January 17, 2006 most exhausts will be cat-back anyway mate so you'll probably need to get seperate de-cat pipes anyhow. as for fuel consumption, it depends on how you handle the increase in power lol Link to comment Share on other sites More sharing options...
