Walker p/n 81850, $500 a piece.

Are your O2 sensors and the wiring in good shape?

Yeah sensors and wires are good. I had issues earlier in the year with bad fuel injector and I think that's what took out the cats. Sensors and bad injectors have been replaced.

Seems kind of steep for a couple of tiny cats.

Yeah. Like nobody replaces them. In the interest of saving $1000 I'd try to clean those suckers, or check a junkyard.

I might just try to clean them. Sadly, jy won't sell cats, it's a federal law or something. Oh and while I'm in there I can put in a set of banks headers!!! FTW lol

Just curious... How many headers do you plan to install on your I6?

question for the electrical buffs here. I want to install a DT switch for the existing reverse lights to be used for back area lighting at night but cant find a wiring diagram for it. It would be so one way turns them on even if not in reverse and then switch it to the other side for normal function.


DISCLAIMER: For the annoying people that will try to flame, this is not to blind tailgators even know they deserve it, so please don't tell me state law, and blah blah blah. thankyou.

I'm don't think you'd need a DT switch. Probably just one throw that controls a relay which gives a constant voltage to the reverse lights when engaged. But I'm no expert at all... Just an idea until someone else chimes in. Also, I think you would need diodes of some sort to prevent current from flowing backwards...

SPST On/On type switch with three connectors is sufficient. Middle to your reverse lights, one side to the NSS output, one side to your fused battery feed. You'll need to splice somewhere into the body harness or maybe transmission harness.
