it's already available through accolade. here is the link:http://www.accolade-usa.com/detail.a...uct_id=04LANH1

looks pretty nice and it should def. show some good gains. although i don't believe that it will be a huge difference over the downpipe. i would like to be proved wrong tho

One thing im worried about if i were to get the header is the cust. service through the vendor. i can say from expereince the RRM cust. service is top notch.

the header kits come with an optional ceramic coating. Otherwise they are just mild steel mandrel bent units. GOing on the fact that the USA is cheaper to get things ceramic coated, that woudl be something to dicuss with whichever RPW agent you choose to deal with or you can organiseit yourself direct with the USA coating agencies.

The system will be made and checked on a car to avoid any CEL problems although to date noen of our systems have produced a CEL problem when used on the 2.0 model vehicle.s

Question

Isnt it better to have the header made of stainless steel?? what abot rusting, or does the ceramic coating prevent that? itd be no good to get a header if its gonna rust. the other thing is, sence its a long tube header, if the car is dropped is it gonna hit the road over bumps?? my friend has some special editon TransAM and i know his hits all the time with a long tube head.

Given the pricing on the header, and comparing it to RRM's downpipe, there is an increase of 71% in price for RPW's header vs. RRM's downpipe. Considering the consensus thoughts that the downpipe gives 10HP, that would mean a dollar-per-HP exact ratio would put the header at a 17.1 HP increase.

The problem here is that RRM's downpipe is only replacing one part; the downpipe. RPW is replacing both the header and the downpipe. Most aftermarket headers for other cars replace just the header and leave the downpipe intact, and will generate somewhere in the range of an additional 10-15HP. Ideally, since both the header and the downpipe are being replaced, AND we're losing the cat, a HP increase in the range of 25HP would be ideal, but I don't think anybody is expecting that. The Header/DP combo should generate more power, but I would think that if it's less then an additional 15HP, it's going to be a hard sell to most people on these forums.

Not all parts give you hp, some will add more value in torque.... I suppose we just have to wait and see, they are making up several different types to see which one is going to give the best "bang for buck" the great thing here is that because they are going to the trouble of making different types and sizes they are going to be able to prove which one does what and not just pull a number out of thin air via a dyno

The only thing I have to warn about on this combo - is that remember firstly, our unit is replacing the header, dump pipe and cat converter as a complete package.

secondly we are working on the equivelent to a "FEd Spec Car" where the australian model vehicles are only running one cat converter, one O2 sensor not like the USA cars.

So what that means is whatever gains we get on our Australian car, will be higher on the USA vehicles due to the inherent restriction in there system running two cat converters.

Time will tell.

Actually, I'm pretty certain that the Ralliarts are only running one cat, but you're right about when that statement is applied to the other Lancer models, which have two. I believe RRM covered this when explaining why they weren't going to build a header. Can anybody clarify on this?

I also understand that there is the potential for added value in torque, and that could certainly weigh in the decision, I just don't have a comparable torque value for the existing alternative to compare against.

Ralliarts are running 1 catalytic converter, and two O2 sensors. One immediately before the cat on the downpipe, and the other at the start of the midpipe.

Well that makes life even easier again then - our numbers and gains shoudl be very very similiar to what you will get in the USA then.
