Good Evening all - I need some help with an Exhaust system replacement. I purchased the Pypes Performance SGG50R (2 1/2" Pipe) exhaust system knowing that it had a 4 bolt flange on the front of the Y Pipe and my OLD Catalytic converter had a 2 bolt flange. Tried like crazy to get a Test Pipe but couldn't find one. I was told by someone that the Monte Carlo SS Cat had a 4 Bolt Flange Front & Rear so I purchased one. When I set them side by side, the Monte Carlo Cat was approximately 4" shorter than the existing Catalytic Converter which had me wondering if the Pypes Exhaust Systems Y Pipe would be too Short. Please see the pictures I've attached. Does anyone know where I can find a discounted Pypes Performance Cat Delete Test Pipe? I think the part number is PVC10. I've tried everywhere. Thanks for your help! Stay Safe!
