FS: DC Sports 4-2-1 Race header w/ casper o2 Sim
Looking to sell my DC sports race header (note: this replaces the cat). The casper electronics o2 simulator plugs into the harness for the post-cat o2 sensor. The thing works awesome, you don't get an CEL's or idle problems at all. The header itself is in great structural condition, with no cracks or bad welds or anything. There is some slight cosmetic imperfection just from rain and dirt, etc but overall the thing is in good shape.
I'm located in Irvine, CA and will also be in Valencia from time to time, or we can work out shipping.
Price is $225 obo for both the header and o2 sim.
Pics down a few posts.
Thanks.

How it works is the o2 sensor that is normally closest to the engine still gets used on the new header. The o2 sensor that was after the catalytic converter (furthest from the engine) get plugged into the harness. If you unscrew it from the stock pipe, follow the cable about 2 feet up and there will be a connector. Unplug it and connect the casper o2 sim (direct plug in) and then plug the sensor into sim. This makes it so the ecu still thinks its getting readings from the o2 sensor. If you dont use the casper 02 sim you'll throw a cel and the car with go into limp mode.
I would really like to sell them as a pair but go ahead and make and offer.

Whoa, 225? Thats cheap. This is a full on race header guys, no longer in production. I'm running this- a must for any NA setup.

I really don't want to separate just because I think the header will be much more difficult to sell without it. If I don't get any bites for a while, I'll get back to you aznprid.
Re: FS: DC Sports 4-2-1 Race header w/ casper o2 Sim
alright cool. in the mean time. ima try the defouler trick i guess. you could always lower price on header alone to see if someone picks it up for less without the o2 as well. anyways good luck and let me know.

^ get the angled O2 defouler off ebay. There are two types, go with the one that shows the difference between his and the other seller on ebay.
