Hello everyone, i just recieved my RRM Header -- i must say nice piece of metal, any piece of advice installing it? There doesn't seem to be any visual instruction around and it didn't come with any instruction, please and thank you.

This has a quick write up if you need a basic overview. Thats about all. I just installed mine yesterday, all I can say is take your time, take out and put header in through the top. If you have GTS, take off the upper strut bar. These are some helpful hints, otherwise go at it! Yoou should be very happy with the final result.

Do the headers turn your check engine light on or throw any codes?

Finished - Header installed -- i do not notice any noticeable gain - my mod are CAI INJEN, RRM Magnaflow. -- even my butt dyno doesn't tell me anything.
2009 Lancer GTS 5spd FED version.

Man that stinks! You would think that you would have felt SOMETHING...??!!!

No you shouldn't. You gain next to nothing to begin with. Mitsubishi did a decent job on the original equipment.

We don't live in the 80's anymore when car manufactures used small pipes and horrible designs. Cars come from the factory pretty much as good as they are gonna get without some ignition timing and fuel map tuning.

Intakes and exhausts doing much of anything are facts of the past when it comes to present day NA cars.

Even on turbo and Supercharged vehicles, ECU tuning is where the power is.

I did not know that....that's weird wild stuff....YES!

Guess I'm not getting the headers then.

But DECENT isn't as good as EXCELLENT!

I have the PZEV version and I can absolutely feel a nice gain from this mod. True to get the most out of it a tune would really put this thing to work but also give the ecu some time to Learn" this new mod. The PZEV header is the only one that will throw codes.

Does your home computer need time to learn new software when you install it? No.

The ECU will see exhaust moving differently and it will say "shit something is wrong and out of my stock parameters" and then it will throw a code.

The gains you get from a full exhaust are very minimal

The ecu has to learn the new parameters for an intake but not a new exhaust system?? I'm not trying to say that this will add 100+ HP but i know that for me there was a noticeable gain. lowend bog is gone.

Same goes an intake.

Put the car on a dyno stock then do your mods again, Your gain will be very little if it even is a gain.

Just put an exhaust on an S2000 dynoed 197WHP stock and dynoed 193 with the intake and exhaust.

Was it a generic intake/exhaust that was used? Is that why it lost some power or was it a well known company? I would assume that it wasn't generic items used....but I'm curious as to why this happens & for only some cars?

Hello again, now i've spoken to different modders about my new Header and even showed them the dyno from RRM -- their advise was -- give it some time to break-in.
Break-in??????? I already spoke to RRM about this and all they told me is the noticeable gain is actually in high rpm range -- so that means i really have to keep pushing the car to rev high up to feel that 8hp and 8lbs torque. **boink***!!!! oh well I guess that's what i get for not getting the EVO instead. Now just wonder if their Turbo is worth the price. Don't get me wrong, I will probably order their other parts, but I guess just not their performance adder, now im even skeptic about the crank pulley and piggyback.

Break in.... :blush-anim-cl: I'm glad you see the bull shit in that statement.

You won't feel an 8hp gain, its also probably crank HP Gain which turns out to be about 6 WHP gain. You also have to keep in mind of the conditions between the two dyno pulls. Where they the same? What was the engine temp? What were the other factors. A common one is to run the piss out of the car and throw it on the dyno for the baseline. then Ice the intake manifold and blow fans on the radiator ect for the upgrade pull.

When you modify your car and are looking at dyno sheets look at the curve. Where does the curve change.


Yes, intake/exhaust mods allow the car to breath better at high RPMS they do next to nothing down low because the stock equipment is good for normal load.

A light crank pulley won't give you any more power but it will put more power to the ground. Look in the main performance section for a thread I started "The truth about underdrive pulleys"

The Piggy back might be good But I have very little experience with these cars but they aren't something special and BASIC knowledge is enough to know that IHE does close to nothing on small displacement engines. Once you stop believing the HYPE and start getting the facts it all becomes easy to understand.

Injen.


The reason is because the factory has put some serious $$$ into developing these cars.

Cars that I have seen lose power because of basic mods.
