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.

like the others have said not exact fit from what I took off but only because the lh gasket is not an grooved oring style. get a 31718 gasket and pop that on there and all is good. Fit like a champ, restored power, no misfires, no p0420 hope it lasts
