What is the exhaust tubing diameter on my 01? I have read two and a quarter and I have read two and a half. What is it, any idea?

As far as I can tell, the 01 thru 04 stock exhaust uses 2.25 " pipe. Most aftermarket systems are typically 2.5" diameter and should mate up the the ball sockets at the cats or mid section. The difference with after market exhaust, which are usually mandral bent should have a constant inner diameter of 2.5" where as the stock exhaust system was not made on a mandral bending machine and has a minimum inner diameter of under 2".

I believe 2.25" is correct...like Ausie said, most aftermarket systems are 2.5" :thumbsup:
