Hi all, I'm on my way to fit a sport cat on my car and thus reduce the restriction in the exhaust system further. My car is a 1.9 JTD 115 hp currently custom remapped with JR panel sport filter. At first I thought I knew where the catalytic convertor location was, but now after looking at ePER I'm confused. Looking here at diagram 1/3 it shows that the cat is number 1, the tube with a 90 degrees bent right after the turbo, that's where I first thought the original cat is located. Now ... after going to diagram 2/3 under number 2 it shows another tube that is right before the main silencer that is also said to be a catalytic convertor and it looks like one. What is wrong, does the JTD 115 has two catalytic convertors (one after the turbo and one before the silencer) or which one of the two is the real cat?
Also where is the lambda located ? before of after the catalytic convertor ?
I've tried searching the forums for an answer but didn't find anything. A simple answer will be greatly appreciated.
