SIKKY RCF Stainless Steel Headers
Attention RCF owners:
Sikky Manufacturing has spent the last year and a half testing and developing a new exhaust header for the ISF and RCF chassis. Our challenge was to design and build the ultimate header from the ground up. Highest power gain, perfect fitment and supreme craftsmanship were our goals.
Our previous header made great power and was no slouch but we knew there was more to be had. This desire to make the best header lead us through an exhausting year and a half of R&D. With the aid of our FARO arm we scanned and created a 3d model of the engine and engine compartment. This is a huge advantage over hand making a prototype like the first header. Designing this header in CAD allowed us to try all kinds of configurations and different tube sizes and lengths. This cutting edge design and testing equipment made things possible that were not previously. After many prototypes and several hundred dyno runs we started to close in on our final design. This process is exhausting but a must in order to achieve our goals. After loads of testing and tweaks with different configurations, we determined that the 1 ¾” primaries we and the other header manufacturers were using for the ISF and RCF were in fact too small. 1 7/8” was the magic number for tube diameter. As a result of increasing primary diameter we expected to see the gains up top and thought maybe we would lose some low end. To our surprise we found gains across the entire rpm range including low end with the most notable at high and mid rpm's. Even more power was unlocked by changing the length of our primaries, as well as collector size and configuration. To ensure we had it right we completed back to back to back runs with these different prototypes and even with competitors headers. Using the same car, same dyno with the same conditions ensured the highest level of accuracy. A stats comparison to our original headers as well as our competitor’s headers made it very clear we had reached our first goal. Obtaining the highest power gain for any header tested on our dyno for the ISF and RCF.
Next, focusing on perfect fitment that would eliminate any rubbing or contact with the chassis or other components. Using a CNC pipe bender, we were able to design and build the header to utilize all single piece tubes except for one runner. Improving strength and reliability and ensuring maximum air flow through the tubes.
Making this header the best it could be required spending the extra time on the little details. We were actually able to make our header a lot easier to install. Saving you time and money. We even went the extra mile to design a very high quality stainless steel cnc bent dipstick tube making this a complete engineered package that ensures like OEM fit and quality. This header will stand the test of time because we constructed it entirely from stainless steel components and tig welded for strength. Little details like our cnc machined groove in the collector flange ensure the gasket and leaks will not be a problem. Smooth and flat head flanges mate perfectly with the cylinder head utilizing the OEM gasket.
This completely new header consists of the following key attributes.
SIKKY RCF HEADERS
A few lucky individuals have had the pleasure of being beta testers for us for the past 6 months or more. Driving on the streets daily with the new headers giving us feedback. The response has been outstanding.
Here are some pictures of the ISF/RCF header for your enjoyment
Merge bullet and CNC machined flange

Couple questions:
-Are these headers throwing a CEL code like the other headers on the market? That is one of my biggest concerns.
-Do you get an exhaust smell in the car?
-Do these pass emissions tests?
-Any high temp coatings being offered as an option?

X2. I'd really like to come up and get these installed if we can get a "no" on these two questions. Incredible deal for sure. The savings in labor costs alone make this a very tempting offer. They look incredible!

Not on any of the test vehicles. One customer has had them for well over 6 months with no cell
-Do you get an exhaust smell in the car?
Not that we are aware of but would need some of the beta testers to chime in
-Do these pass emissions tests?
Yes
-Any high temp coatings being offered as an option?[/QUOTE]
yes, but not a standard offering so will add two weeks at time of order

Me & You Both, i think i'd be up for a LONG road trip. We're Both waaaaaaaay down South & to drive to Balt. Maryland would be a LONG trip since i usually Fly if a road trip is longer than 5 hrs., i'm not one to drive & take in the scenery. But this just mite be worth it, especially if they threw in a few incentives. I'll be a Test Mule!

Hey guys, I have been one of the testers of these headers since February I believe.
They are awesome!!!!
The headers cause NO check engine lights!
The only smell is the normal exhaust smell from removing the primary cats and that only happens when you really get on it for a while...and believe me I like to open it up! Lol!
I've been on CL since '06 and loved my SIKKY headers on my IS-F. I am VERY impressed with the power I feel in my RC-F! I was worried about the gains considering the improvements in the RC, but I have been truly amazed. The team at SIKKY and JE know what they are doing and talking about which made me feel very comfortable leaving my RC-F with them.
Any questions let me know!

After reviewing the logs IM TOTALLY DOWN. Question is how long does the install take? You're roughly 14 hours from me, so I need to plan accordingly. Johnny, if you're down maybe we could do it this fall?
#10
C, i'm going to trust you to check everything out & IF you think it's worth it, then i'm IN! PM me with anything you want to discuss & we'll work it out when it fits both our schedules if you want to. I need to put some miles on mine anyway & i Love a Good Road Trip! But, i'm like you i need to know about how much time we're looking at here.

How is the coating applied?
#15
Yes the test car was stock other than an Apexi intake silicone tube which in this case it might as well be stock.
We don't do the coating here. It is applied like most ceramic coatings. The process is lengthy. First they therm the headers and clean them. Then they get blasted, then a base coat, then the finish coat and a whole lot of polishing with a final wipe down and cleaning. It's quite the process. Glad we don't do that here!
