Q: I need to know what size exhaust gasket to get

asked by on

I bought an aftermarket exhaust for me car used, so it did not come with gaskets. I need to know what size gasket to get I believe the piping is 2.5" but the confusion is. If I get a gasket that size wouldn't it be too big to fit onto the old part of the car. The new exhaust is a cat back

Hi there, thanks for writing in. If your new exhaust is cat back, then you will have the factory flange on the back of your catalyst. I recommend just getting the same size as the factory one you removed.
