Anybody thought about

this ...

Power FRK HP2 Sport Performance Header & Collector Kit | Power FRK USA

Not sure about the FRK unit (many opinions on the other forum and the problems they're reporting having with the K1300s worry me a bit) but kind of like the idea of the header and keeping the original can.

Thoughts?

Don't know of any takers on this combination. the FRK module has been discussed at length on the R11/12S forum. Some have stated it is nothing more than a spoof on the temperature sensor. As for the exhaust system, most have gone with the Akrapovic.

Agreed, not a fan of the FRK module. Tried to make it through all the discussion on the other forum and quickly lost interest.

I do however like the header. My preference would be to keep the stock can as I think it really suits the bike. I know the Akra stuff is nice, have had it on other bikes, but the end can doesn't show a lot of imagination. Looks like it could just as easily be an aftermarket can on a CBR. On top of which it protrudes out the back just enough to ruin the lines of the back end for me.

Beginning to think my post wasn't particularly well thought out. Ultimately, the name Don de Vink is new to me so of course read the write-up with some suspicion. Header looks to be of nice quality in the pictures, but was wondering if anyone might jump in with something along the lines of - "Oh yeah, Don de Vink that guy knows his stuff can't go wrong with something he's put together".

Then again it may be that anyone who's looked at the link did similiar to me and thought never heard of the guy and therefor didn't have an opinion.

Cheers,

Pete, you are correct about the FRK debate on the 11/12S forum. As for the Akra, right again. While the function and exhaust note are an improvement, the form lacks any artistic attempt to blend in with the design of the cf tail section. As for the headers, eliminating the cat on a bike in warranty is my biggest concern. Not going to go there at this time with my HP2S. I do see that the flapper valve will be installed on the RT/GS version of the DOHC engine. I did flip the control cable over to temporarily disable the valve and found it to be of minimal effect.

Pete & Bubba,

My thoughts about a FRK-module is that is not fine-tuned like a Rapid-bike module (or other adjustable modules), so the A/F mixture is a guess (every other motor is slightly different), you both know that BMW engines are running lean and putting an other exhaust system, catsectomy or catless heathers on the bike ... the bike run's leaner than before ( leaner is hotter with possible damage to the valves or/and pistons)

(Bubba ... you know) I'm running with a Full Akra system (this system is developed by ... Don de Vink !!!) and a Rapid Bike module, fine tuned on a dyno (Tovami, Ruud Fredriks) so I'm sure the A/F mixture is more then okee

Got a lot of bottom power and no big hole in the torx curve

Running with or without the butterfly valve makes no difference, the valve is developed to be a noise reduction device for going true the EURO norm tests !!!

Jack, I'm pretty committed to leaving my HP2S stock except for some suspension tuning. No A-arm mod. I sold that option to Shreddr.

Thanks guys,

Again, wasn't really interested in the FRK module; was interested in the headers.

I'm with you Bubba in that I want to leave the bike more or less stock, but am always interested in letting them breathe a little freer. The header seemed like a great way to do this while maintaining the stock look (which I am over the moon about).

While it's nice to see that someone is familiar with Don de Vink's work, I'm still skeptical. You would think a page that uses words like lethal to describe the power would at least post a graph or two.

I think for now I'll stop "shreddring" and enjoy what I have. I think my problem is I picked this bike up in November and given the crappy winter we've been having haven't really had a chance to ride it so am otherwise entertaining myself.

Cheers,

I'm still thinking that ... a Rapidbike module (or some other A/F fine-tune divice) brings the bike up to do what it had intended to do

in combination with catless headers (stock can or not !) (and a good A/F mixture) the bike runs free, no hick-ups, no hesitation ... not in the low RPM, middle and end RPM ... from a cold start to a warm engine

The headers from Don de Vink are re-designed Akra headers and do just a little better than the Akra headers (and that in combination with the stock-can)

Yesss ... I want to experiment with a longer (5 mm) paralever strut (ABD) and maybe (when I can get one second hand) a RT A-arm ... (can build it back any time !!!)
Also (when ... I touch the road with the cilinders) I want to increase the ride hight at the front and rear (in combination with the paralever strut)
When it is not what I expected ... I can undo the mods any time
