Its just a section about 20mm wider than the rest of the pipe; could just be a join or something. In which case, I have no cat! Is this ok?? I thought it was illegal??

_scott Member 21 Member For: 16y 7m 24d Gender: Male Location: WA Posted 29/08/08 09:46 AM Author Share Posted 29/08/08 09:46 AM Oh ok, but yeah I dont even think I have a cat to speak of. So would this decreased restriction be making my car run better or worse? because the exhaust creates back pressure which makes the engine run better right?

Ill definitely be having it fixed, hopefully sooner rather than later. I was just kinda hoping that this might be the cause of some idle issues Ive been having. Time will tell I guess!
