You need to be prepared for the work needed if you buy this piece. As it is a 'universal fit' rather then the 'Direct Fit'. Check & compare overall length to be sure. Will possibly need to make a pipe end shorter to fit. Also does not come with hardware, flange, gasket. Best to weld connections together but can be done with clamp & exhaust sealant.

Can't tell anything about quality but not really important to me since is a 5 year warranty product. For some reason could not buy it online, maybe not Advance auto's fault but some of ours federal dictatorial EPA regulations. IMPORTANT: flange in this product is thinner than OE, make sure you use some washers to make up the gap difference under the 6 bolts. Is going to leak if you do not do it. Trying to overtight it with no washers can damage your head's threads.

The converter is nicely made, it welded in very well and was a good fit. It cleared my code for down steam 02 sensor. I can't say anything but good about it but need to see how long it lasts for a solid opinion. Magnaflow offers a heavy metal version that has better catalyst that may be a better choice for longevity. I did not know this before I bought and installed mine.
