Not sure about not triggering the check engine light.. But, random technology makes some pretty nice cats.

I recently installed Magnaflow cats (and new O2 sensors) with no problems.

Ag, did you use them in same location as stock cats with stock manifolds or are you upgraded with headers? Would love to see some pics regardless!

Replaced VRP log manifolds with Eurocharged mid-length headers and the cats are located in about the same position as the OEM's. Secondary cats and resonators were deleted several years ago. Secondary O2 sensors are switched off.

I am also running Magnaflow front cats, direct fit bolt ons with PLM shorty's. Magnaflow part numbers 24334 and 24335. I replaced all four O2 sensors with new bosh sensors during the install. Good luck with your install!
