The catalytic works perfect . But you have to do so extra work to make the sensor not to touch the second muffler , beside that works great and great price

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.
