Nic Posted September 27, 2007 Share Posted September 27, 2007 even with the boxs still in? which cat do you remove if only one then, and do you know of anyone who supplys decat pipes? The NA is a lot louder when decatted compared to the TT, on the TT the turbos quieten the exhaust note a fair bit, it'll depend which exhaust you have fitted just how loud it will be. The first cat is the most restrictive of the 2, so this would be the one I'd remove. Don't expect big gains, it'll give you a little more response. Your other option would be to fit a tubular manifold, these replace the stock cast manifolds AND the first cat. These are good for around 8-12hp gain. http://img98.imageshack.us/img98/8473/p1030161sa4.jpg http://img89.imageshack.us/img89/1831/p1030162uk1.jpg Envy probably also do decat pipes for the NA, try contacting Gaz Walker Link to comment Share on other sites More sharing options...
