whaaat? i realize drastically lengthening a wire could possibly increase resistance, but we are talking inches, perhaps a foot at the most and soldering the connections. what would be the delta resistance: it would be so little it would hardly register as any change at all even on a super precise ohm meter

yes, don't lenghten the o2 sensor wire by like 200' feet and use butt connectors, but short of that, i think your gravy..............unless any EE's can prove me wrong

 

yes as greenpsycho said, your probably best off lengthing the wire if you do get the mirage header/dp, it will cost next to nothing as opposed to the $40-60 it would getting a new bung put in. if im not mistaken, the wire will have to be lengthened about 2ft, the bung is at the end of the dp, just before the flange to connect the cat.

 

yeah but im scared i might break it though? well im still thinking of getting the mirage header/dp or just get the rpw race headers but we'll see whats happens

 

the rpw race headers are definitely not worth what you pay for them, i very highly doubt you will get more gains out of their headers than anyone elses. if you plan to buy some that are specifically for the lancer, do yourself a favor, save some money and either get the rrm (does not come with dp), or the kamikaze (which do come with a dp). then put the money you saved from buying one of these headers toward a piggyback ecu.

 

thats a good point though but i've read here in the forums that the rrm & kamikaze all cause the cel to come on is this true? how much is a mirage header/dp anyways?

 

all aftermarket headers made for the lancer will cause cel. your stock manifold has the first cat in it, by removing that, the second o2 sensor reads the exhaust as having a heat up prob, so you would either have to get a mil eliminator for the second o2 sensor or you could do the anti fouler trick.

 

do you know any vendors who sell mirage headers?

 

there was some person selling them on ebay for a while, but she had such bad feedback you wouldnt want to buy from her, im not sure where else you can buy them from. those mirage headers will also cause cel. you can get the kamikaze from ptuning.com for 259 shipped, for the black temp coated.

 

yah i might go with the kamikaze then

 

thats what i have, i think they work fine, you dont get much gains from them, but get a piggyback ecu, and you can get the most out of them.

 

AAAAHHHHH, dude, just sssshhhh it, you are spreading SOOOO much bad/misinformation


first off, rpws header do offer increased performance, not in HP, but in torque because of the design by itself. its just a fact. and when you go super (like i am) the runner lenght and design really makes a difference, in fact ripp told me they've measure about 9% change in torque on our size engines, which could mean the difference of 20 lb/ft when your pushing stage2.

second, aftermarket headers do not cause the cel, is the removal of the first catalytic converter in the stock extractors that does. if you are smart about it, there are several cheap/freey ways to counter this, ergo, any header could or could not cause cel, its just up to the user. but because rpw places its 02 sensor bung on a single tube instead of on the collector like kamikaze and rrm, most people found in the stock configuration, it will not cause cel

kamikaze and rrm headers are very VERY much alike. but kamikaze comes with dp and is cheaper

 

What misinformation? all the info given is opinionated, you have yours i have mine.

that little bit of extra tq that the rpws will give will not make much of a difference, and in MY OPINION are not worth $500+.

i doubt that he will run a supercharger, ask him. most people that would spend money on forced induction will not spend on supercharger, because you have that really queer sounding whine from the belt.

i told him that removing the first cat will cause the cel (it is because the aftermarket headers do not have a cat in them), read the posts thoroughly before saying anything.

my review of the mirage header just might help

 

oz4g94 - he's right. A lot of stuff you said is just plain wrong.

RPW headers - the best available. Completely worth the money. They have solid design. RRM and Kamikaze are both shorty headers. While they're nice, they aren't the best.

CEL - some headers don't cause it. Even RRM and Kamikaze. It differs from car to car. And there are other tricks to bypass it.

etc etc.

 

I think you're on the short side of the info here, oz4g94. If anyone has an independent dyno claim that can put the kamikaze header near the 17whp gain from RPW's I'd be seriously impressed. RPW has the design and racing experience, R&D and dyno proven results to back their product. Is Kamikaze a good buy if you want to save money? Sure. But if you want real gains I can only think of RPW as the best buy.
