I have not installed the products yet but they do seem to match up side by side with the old cats that fell off the car. Also the quality looks good.

Great replacement for stock cats. Noticed significant increase in power and good sound with Flowmaster muffler . No problem with codes from o2 sensors with new parts. A lot less expensive then stock factory parts.
