Kaan W Posted November 9, 2012 Share Posted November 9, 2012 I was just wondering as I need an MOT but I have a decat pipe from the single turbo setup. I still have the origonal cat but does this still fit with an upgrade like this? Or will the car pass with just one cat after the down pipe if that fits?

listy Posted November 9, 2012 Share Posted November 9, 2012 Not sure about a single, but my TT gets a reading of 1.1 with a double decat. Pass is a 1.5 Quote Link to comment Share on other sites More sharing options...
Kaan W Posted November 9, 2012 Author Share Posted November 9, 2012 See the bloke gave me this when I bought the car and said you can either find a friendly test centre or go through the hassle of fitting then removing every MOT. Just cant see how it would fit if its a 3" pipe right through on my current set up. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted November 11, 2012 Author Share Posted November 11, 2012 After looking at my cat theres no way it will fit unless I use a 2.5 - 3" adaptor from the cat to the rest of the exhaust but the downpipe side of the cat has a 3 bolt flange I might just sell the 2 cats and find a high flow cat. Does anyone have experience with this sort of thing? Quote Link to comment Share on other sites More sharing options...
Benjy Posted November 11, 2012 Share Posted November 11, 2012 Yeah. They're about as much use as a chocolate baking tray. Best off refitting cats for test, or finding a friendly MOT man. Gaz might let you know who's offered him some assistance if you ask him really nicely and promise not to tell anyone! lol Quote Link to comment Share on other sites More sharing options...

Will be better off just not using them. I will see if there are some test centers that will help out Quote Link to comment Share on other sites More sharing options...
