RedT18 Posted March 13, 2010 Share Posted March 13, 2010 Hey guys, I am new to the board and have a question concerning the front exhaust section. My J-Spec supra is equipped with decat-pipes made from mild-steel. Do oyu know where i can get new decat pipes in 3" and Stainless steel? I only found 2,5" pipes or pipes for the UK-spec. thx for your help! Quote Link to comment Share on other sites More sharing options...
SteveC Posted March 13, 2010 Share Posted March 13, 2010 Hi there, Paul Whiffin of Whifbitz could probably supply or get a pair of 3" stainless steel J-Spec decat pipes made up for you. You could drop him a PM. Quote Link to comment Share on other sites More sharing options...
RedT18 Posted March 15, 2010 Author Share Posted March 15, 2010 I wonder if there's just a difference between the UK and J-Spec downpipes or are the frontpipes also different? Quote Link to comment Share on other sites More sharing options...
SteveC Posted March 15, 2010 Share Posted March 15, 2010 1st decat: You need the correct one for a UK or J-Spec - they're NOT interchangeable because the stud holes are different. 2nd decat: Either pipe will physically fit both UK and J-Spec models, but on a UK model the 2nd cat has an O2 sensor, so you have to have a decat pipe with the gland for the sensor. You can use a UK 2nd decat pipe on a J-Spec if you block off the O2 gland with a plate - or you could use the gland for a sensor for an AFR gauge.

RedT18 Posted March 15, 2010 Author Share Posted March 15, 2010 thanks a lot! I think I will go for a UK spec 2nd decat to have an extra AFR gauge. Quote Link to comment Share on other sites More sharing options...
