"This isnt the catalytic converter i needed. I needed the main cat and the post made it seem like this was the right part. Chances are youll be needing the main rear cat so be sure. This isnt the greatest review bc they failed to be descriptive on the part. If your car pulls a code saying your cat needs to be replaced dont buy this. Its just the front pipe." posted by: on October 28, 2013 view all 2 reviews

"Replaced entire exhaust and this item was part of it. Couple days for shipping arrived undamaged had everything welded and installed and sounds great. This is a fraction of the cost of a direct fit/bolt on converter so was pretty much a no-brainer." posted by: on May 18, 2014
