BlackWatch66 Posted August 13, 2015 Share Posted August 13, 2015 Hi guys, I have a stock TT with a stock exhaust, and have just purchased a double decat exhaust system with a 1.2 bar RR, will I be able to fit this system without any problems or any other parts? Thanks Link to comment Share on other sites More sharing options...
mattdavies Posted August 13, 2015 Share Posted August 13, 2015 You need one of Chris Wilsons Fuel cut defenders if you dont already have a aftermarket ECU and I would fit a boost gauge if not already done so just to monitor whats going on.

BlackWatch66 Posted August 13, 2015 Author Share Posted August 13, 2015 Thanks Matt, my other concern is if the 1.2 RR is too large and I need a 1 bar RR instead? Link to comment Share on other sites More sharing options...
mattdavies Posted August 13, 2015 Share Posted August 13, 2015 Yes I would start with a 1 Bar and then use a boost controller, I think you should be fine with a 1.2 bar as you 'should' be ok upto 1.25bar. You can always save and get a boost controller later and fit a 1bar ring, its not hard and its cheap Link to comment Share on other sites More sharing options...
BlackWatch66 Posted August 13, 2015 Author Share Posted August 13, 2015 Is the FCD absolutely nescessary at the moment just to have the exhaust fitted? Link to comment Share on other sites More sharing options...
mattdavies Posted August 13, 2015 Share Posted August 13, 2015 Yes, over 1bar you will hit fuel cut. and the first time you do it you will probably scare yourself as it hits hard !! If you are trying to avoid a FCD then I would fit the First De-cat and leave the rest stock, the reason for this is the first de-cat is the hardest to fit. With the second Cat in and stock exhaust you will only potentially hit fuel cut on Cold night motorway pulls. Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 13, 2015 Share Posted August 13, 2015 I have ONE left in stock if you need it, probably won't be able to make more until middle of next week due to other work.
