Does anyone know 100% for sure what size our stock exhaust piping is? I need to put in a universal catalytic converter and I need to know what size inlets I need to buy... And my car sitting on the ground is basically impossible to get under it and check. Thanks!

just changed the gasket that goes between cat and rest of the exhaust. I measured the pipe opening, comming out of the catalytic at 2.75"

no, it can't be 2.75 its 2 1/4

2 1/4 at the mufflers, 2 3/4 coming out of the cat. only 1 pipe comes out of cat then splits when it hits the resonators. Tape measures don't lie

didn't know he wanted the size at the cat.
