Hi Bill, I'm glad to help you! This Walker Intermediate Pipe (Part # 55354) has an inside inlet diameter of 2.25-inch and the outlet diameter are 2.5-inch.
Is this a pipe to fit in where the catalytic converter is as a test pipe?

Hi Candi, I'm glad to help you! We can only look up by the vehicle. Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.
