Q:Does this muffler have a single 3 inch inlet and 2-3iinchoutlets? outlets Show Less
Stanley N.
A:BEST ANSWERHi Stanley, I'm glad to assist you. The inlet is 3 inches, and the outlet is 2.25 inches in diameter. Do you need a universal type with the dimensions you noted? Or do you need a direct-fit muffler? 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, and engine size). Still, it is best to call our parts specialist (for real-time, live, and immediate assistance) on our toll-free number, 1-866-529-0412 (Monday through Sunday). Show less
