Was a basic bolt in, had to replace both O2 sensors, because of their age and the rust. Have seen an improvement in gas mileage.

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.
