99-00 SI Header/Exhaust question
Ok so I have an 00 SI with Tanabe sRacing Medallion Exhaust. I just picked up a Replica Tri-Y header and before I try to install it I want to know If I need a test pipe or will it bolt right upto the stock cat?

Re: 99-00 SI Header/Exhaust question
Is the flange on the header at a 45* or at a level sitting position? I'm thinking that the cat will be at a 45* if it's stock. Was on mine anyway. The cat looked stock to me. I could be wrong though.
