I'm seriously considering purchasing a low mileage 02 or 03 RSX TypeS, but before I drop the cash and sign the papers I want to know how the aftermarket is supporting this vehicle. In particular I am looking into headers. I know a 4-2-1 wont show much improvment over a stock unit and a 4-1 race header eliminates the cat. Here's were the problem is: I'm not sure if I'm the only one, but I don't like driving around with a big, ugly, yellow-orange Check engine light all the time. Are there any 4-1 race headers that include both 02 sensor housings so it wont throw a CEL? Or will the 2nd 02 sensor pick a signal showing that there is no cat at all? hmmmmm..... Hondata K-pro? thanks.

 

Hmm....no one seems to care I guess. Well, I checked out toda and they make a header that does. Pricy though, but what can you expect from a company with great parts and an even better reputation. I love the RSX I WANT ONE!

just remove the bulb = problem solved and its free.

 

Forgive me for sounding like a moron, but I'm still new to this; remember, I have owned three cars that were obd-0. Anyway, I heard that driving around constantly with a check engine light on can mess things up and do things like make your A/F ratio run overly rich. I'm not sure if this is true, can someone please explain.

 

To answer your question, all the race headers specific for the k-series have two O2 sensor bungs for your sensors. The primary (nearest to engine) O2 sensor is the one that detects your AF ratio. The secondary O2 sensor detects if there is a cat still on the car or not. Race headers trigger the secondary O2 sensor to make it have a CEL.

Performance is not compromised, the CEL does not appear immediately after starting up the car after the install. Instead, it comes intermittently. However, there are certain O2 simulators (Casper's, DIY mechanical, or buying a mechanical) that seem to work. They are not 100% guaranteed to work but they do help you get rid of the annoying CEL light once you have a race header installed.

But yes, Kpro will help you get rid of the CEL if you turn off OBD2. Kpro's a pretty nice addition to any Kseries car.
