I have stock gutted cats on my 02 Z right now. I want to weld in a piece of pipe in each one to make it flow through. Can somebody tell me the size pipe and what length to get to weld in them? I want to be able to take it apart and do it all in a couple of hours not take it apart and have to go buy pipe. Thanks. I cant just take them off and put an offroad pipe in either I need them for inspection.

b-ron

why put a pipe in them just gutt them out it will be going straight through anyways

i read on here that the open cat causes turbulance in the flow. i dont know if thats true or not. so i was just going to weld some pipe in there to make sure.

i need to use my cats. i have to pass nys inspection. plus i dont want to be pulled over and for some reason the cop looks at my exhaust and i dont have any cats. im guessing the pipes i need are 2.5 inches in diameter.
