ok so im taking my cat off and I am going to be replacing it with a straight pipe. I need to know the diameter of the pipe coming into the cat as well as out. If anyone has done this and knows the exact distance that would help too.

Thanks

 

well you can either do that of just undo the exhaust out behind the cat and bust the cat out. thats what i did on mine. incase you need a cat for inspections. some inspectors look for that. some dont. but i believe the pipe is a 3 inch pipe. and the length all depends on where you cut it at.
