From Vermont
Fit perfectly first time, includes gasket part number 31718, is CARB compliant, met standards for vehicle inspection and turned off all warning codes. Vehicle now sounds quieter and runs smoother, also increased gas mileage mostly due to the fact that it was running poorly with malfunctioning catalytic converter. Advance Auto web site was user friendly and ensured the right part as long as you correctly identify your vehicle. Saved about $400 on price for same part from dealer. Overall very positive experience. Now waiting for my extra $25 from Advance for my next purchase.

Top quality fit and finish, O2 senors holes in the correct locations. 2-peice design made installation straight forward. Everything you would expect from Magnaflow....except...hardware is not included. Fortunately I was able to remove all the nuts and reuse them. Considering what this costs, the least they could do is include new hardware. I would recommend this product, but get new hardware also. Would've put 5 stars if it included hardware.

The spec is incorrect. The Inlet is 3 inches, and the outlet is 2 1/2 inches. If you choose the 2 1/2 inlet there will be a flow restriction. If this is of any concern, use the 3 inch inlet, outlet converter, and an adapter on the outlet to bring it back to 2 1/2 inch pipe. Good product!

This is a good aftermarket cat that you will have to modify to fit your vehicle. This a universal cat that is determined to be an exact fit based on the engine you have in your vehicle and it's displacement. Exhaust flow rates will be different from a 4 to a 10 cylinder which means that all parts of an exhaust system have to be sized to meet a minimum flow rate to allow the exhaust gases to pass through without causing restrictions and hurting power and gas mileage.
