OK, my next goal is to attack the exhaust. I want an RRM header, but I'm not looking forward to having CEL (technically "Service Engine Soon") on all the time. If a real problem should occur, I'd like to be aware. I searched, but didn't find this exact question, so I'll put it like this:

Those of you who have had RRM's header for awhile, how many have CEL issues?

Thanks for the input.

 

well all do you can buy a mil elimamtor for 15 dollars if it bothers you

 

Meh. From a search, I haven't seen good things about MIL eliminators. A lot of complaints popping up.

 

i thought the raod race header had a o2 sensor hole ?

 

Still says "may cause CEL" and I've heard lots of people say they have the light come on. I want to avoid that.

 

I t will come on its the lack of change in exhaust gass tempriture from the 2 o2 sensors that cause it no way around it.

 

just get the header, you wont be dissapointed. after taking my header off before i got rid of my lancer. i noticed such a huge loss in power. you will love dropping it into 3rd on the freeway

 

well my cell light comes on at least once a month and i just reset the battery, sure it takes about 15 minutes, but thats the only way i found to get that damn light off.

 

So even with the CEL issues, it's definitely worth having?

 

the headers are definatly worth it, i have the kamikzi ones and i love them! dont worry about the CEL just get them!

 

can i just take the CEL bulb out? i mean do i really need it that much and will it cause any problems if i do take it out?

 

You could just put black electrical tape over the dash where the cel is too, but i think an cel eliminator is a much better solution. At least that way if your car throws an error code that isnt related to the o2 sensors, youll be able to see the cel and know something is up with your car. Just my thoughts on the issue....

 

what in the car can actually make the cel go off? if its intake or exhaust then it doesnt matter

 

Exactly. While my Lancer is no POS, my last car was. When the CEL was on, something was seriously wrong with my car and I then knew to A) check it out and B) fix it (2 examples - O2 sensor went bad causing car to run rich; engine was dying). With a constant CEL or no bulb, I won't know until something breaks.

 

You need to do more research, its not just exhaust or intake. Any sensor on the car, dealing with the mechanical systems, can show an error at which time the cpu will throw the cel. There are millions of error codes that can throw a cel. The point is the car can "diagnose" itself and visibly show something is wrong, even if the problem isnt visible.
