Man... i'm sick of reading the same ol reviews that just aren't helping me decide. I need to know which set of headers to get.. rpw or rrm?! I mean, i'm thinking about rrm because i'd like to be loyal to them and give them business, but on the other hand, its smarter to buy the better product.. Both are about the same price buy RPW comes w/ the downpipe as everyone knows.. I just want some new feedback from some people or something. I'm not really interested in the Kamikaze headers but if you feel like you need to try to convince me that they are the best, you can try. And, as of right now, i have no plans of going Turbo. So any extra help i would appreciate.. Thanks guys.. Peace

 

Do a search about the downpipe from ROCK. Basically he stated the he/RRM investigated and made a few downpipes... all in all there were no gains to notice so he abandoned the idea. Instead of thinking about the downpipe you should consider future mods. RRM header can go with RRM Turbo kit...RPW header cannot go with RPW turbo kit. Your choice on this but don't want you worrying over downpipe when there isn't any real gains to be had by it... It is more of an advertisement ploy to get you to go one way more than the other. Like buy these CD's now and we'll include a free toothbrush! HAHA!!

 

So, say i was gonna say that i'm not gonna go turbo.. doesn't that downpipe become a table turner toward rpw?? The other things i consider are... RRM has the better finish.. the chrome look instead of that dull **** like rpw and kamikaze right?? So hm... i guess when it comes down to it... i have been dealing w/ the downpipe issue... I mean, i believe RRM if they said there are no gains... but does that mean theres not big gains? or could it be only like 2-5 horse?? Cuz w/ RPW, you'd get a better price and that free power and from what i've read on RPW's site, the bigger gains..

 

Having driven and RPW car with header and downpipe i experienced more loss in low end torque/power due to supper open flow... on the top end there seemed to be about the same pull as RRM header. In mid range was where i noticed the real difference. RRM's header started pulling around 3400RPM. I really didn't feel RPW header pull until around 4200RPM. Then as i said above the pull felt equal to the RRM header. My take on it is that i'd go RRM because it gives you a better range of power than RPW. The real test would be to drive RPW header only against RRM header... but since they produce header with downpipe i havn't come accross anyone who hasn't used the downpipe. I have read that RPW specifically designed their header for high end. I know for a fact RRM designed theirs centering on the midrange. With an FPR i experienced huge gains on the RRM manifold. I don't know how the RPW would do with an FPR. This is all i know and what i felt. PM some RPW guys and see if you can concure "the pull" factor. I know RRM guys will back the RRM header pull range. Good luck!

 

I don't mean to sound like an ******* (but I probably will sound like one anyway), but if RRM found no gains, does that imply they dyno'd their header? I've been totally unable to find any info on that for comparison to the RPW dyno that (i think) wags had done.

Anyway, personally I think RPW's rep R&D, and the dyno proven gains speak for themselves though I've never heard anyone complain about the RRM header and the Kamikaze is quite decent despite first batch fitment issues (and nicely priced as well). Read what's out there, weigh the pros and cons yourself. I think you'd have equal results if you flipped a 3 sided coin.

 

Yeah boe well.. you've pretty much convinced me already.. hah damn.. however, the poll is still 2-0 RPW.. Those RPW should leave some imput on this and make it a debate.

 

Yeah, i have read everything i think... all the info on RPW's site sounds real nice and they say they make the biggest gains... but RRM is Famous for top quality.. kamikaze is probly more known in the big picture for headers... and has a better price.. but ****, Can it be true that a downpipe does not create any gains? thats hard to believe... however, i dont know much about that **** so who knows

 

(I voted RPW)

And Kamikaze has a downpipe too for the record.

 

according 2 rob there header puts out around 15whp where as the rpw is dynoed at 19whp and had the same ammt gain in tq i havnt driven rpw but i think rpw would be just a hair better

 

and ryan... aren't you the one that had the RRM and hated it and sold it? are you gonna get the RPW?

 

well someone said rpw is a high end power maker wich in my view there is no high end on a car that red lines at 6k more twords low end tourque and a little bit of back mrpessure on a NA car help the stock down pipes restrictive ness adds a bit of tourque and then the gutted at adds some hp

you got all free flowing crap and you get no back pressure then you loose low end tourque witch is what gets you there
and lets face it with the lancer you need to get there then worry about stayin there

RRM

 

yes i sold mine and am going rpw when money is in the bank or if i go custom turbo ill get a turbo manifold made . also rrm has a small design flaw the o2 sensor socket is 2 low that u have 2 put bolt in upside down basiclly not a big deal just anoying when taken it off or on cuse u have 2 use 2 diff sizes sockets

 

I'm gonna chime in on the side of RPW here. There is a definite pull in the higher rpm range. Right around 4000 is when I can feel the car really start to take off and it doesn't let up until I either get off the gas or get upwards of 120 mph. Low end torque is killer now too, and I'm almost willing to bet I can outrun a similar Lancer with a header minus the downpipe. I haven't had a chance to drive in or drive against a car with the RRM, RMR, or Kamikaze header, but that chance will come at the end of the month.

I'm almost willing to bet that the RPW produces bigger gains because of the downpipe and the longer piping it affords. How can it NOT? Take a look at the stock downpipe if you get a chance and you'll understand why. I mean, don't get me wrong. You can believe the hype from either RRM or RPW; that's marketing for you. What matters in the end for me though, are the numbers. 15whp<17whp.

As for the looks of the header, you can get the RPW header ceramic coated just the same. In the end, I chose RPW and I think I made the right decision.

 

Man, I was going to start thread about RRM and RPW header, but you beat me to it. I too was a bit confused on which I should purchase but my gut feeling tells me RPW. I like the look of the RRM header, but just like ghostrider said, I can always get it ceramic coated. 17 whp - I didn't know it was capable of making such a high number. That figure convinced me even MORE. I should get the header next month.

 

well i just got the kamikaze and will be installing it sunday. you can get it for about 260 shipped to your door. i'll le tyou guys know what i think after the install.
