Q:I am looking for 2 1/2" inlet and outlet ID will this cat work?
MICHAEL K.
A:BEST ANSWERHi Michael, I'm glad to assist you. Most of our direct-fit catalytic converters have no dimensions noted. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, 2WD/4WD, and engine size). The VIN would be helpful. It is best to call our parts specialist (for real-time live & immediate assistance) on our toll-free number, 1-866-529-0412 (Mon to Sun). Show less
