r1200s exhuast options

[rouxfuss]

Hi I recently purchased a new r1200s with all options I am looking to replace the stock exhuast , what are most people running ? the dealer likes the akrapovich slip on and is suggesting the warranty would be void if i went full race or evo . does the full system remove the 02 sensor? do you need a chip/power commander if you go full system?I am sure theese questions have been adressed else where on this forum but my search has not returned theese answers . What other upgrades are must do? thanks for your responses and i love this bike . ride safe

G'day and welcome!

I typed in "r1200s exhaust options"...nothing
then "12s exhaust"...nothing
then "silencer"...

...ah yes here is a nice little list

I am sure if you type in "lean" in the R1100s and r1200s forums you'll get some good stuff

dont type in "which oil to use"
or "what tire" ... you'll never get out of here with your mind still intact - heh heh

I have Remus can, the bike runs a little lean, the sound is good but I wish I had either got the Zard or waited and got the full HPE - the HPE looks wikkid

here's the list you could search for

Remus
Staintune
Akropovic
Laser
HPE
Zard

...some else may know of more, I might have missed some - hope this helps you a little, enjoy your bike!

I tried a search on R1200S and Laser and got quite a few threads...

Especially if you are spelling exhaust wrong...

Akrapovic full exhaust system is top notch. Great quality and performance. Sounds good too!

+1

As that is the system I have.

PS: HPE for me (impossibly cool as only Italians...etc etc). Hate the curvy (60's look) OEM header stuff.

PS: ponies AND middle range AND ...erm...that lean mixture thing > search for RapidBike (kinda a Power commander thing).

PS: why pay zillions for titanium? (adds only 0.00005678 mph - according to my recent scientific research).

Might want to put a location in your profile so we can tell what part of the world you live in. Helps to evaluate dealer comments and gives us a frame of reference for your questions/comments.

What I did was install the Remus header and keep the stock cans, which I like. Gives a bit more sound without angering the neighbors. I guess I've out grown the joy of blasting cars when I pass. This leaves the O2 sensors, gets rid of the cat and does not void the warranty.

[Pete B]

I agree with Peter F on the HPE stuff. In fact I ordered the HPE in titanium from M Tec last May. Since then I have received no exhaust and have been billed not once but twice.

Communication has been spotty at best. They claim to have sent something but were never willing to provide tracking numbers or any updates. Needless to say this is now a dispute being worked through American Express.

I cannot recommend strongly enough that if you are looking to purchase the HPE stuff that you do it through someone like Sandbar and NOT M Tec.

Bob Hancock:

What have you noticed in terms of performance with your Remus header/stock muffler?

Does it improve power in the low end/mid range/smooth out the 5K spot?

Or does it lose power in the low/midrange area but gains power higher up in the power band?

In closing, I am familiar with the performance of the Laser header system; however it does not look as nice as the Remus header system. In closing, your feedback will be helpful.

Mike, I'm afraid that all my "data" is from my butt-dyno so it's not very precise. When I got the bike I put the foam air filter in along with the Remus header. The bike feels like it makes the same power at low to mid rpm but has a stronger surge when it hits about 5500 rpm. It really comes on pretty strong. The main diff I notice is a bit more sound....like a motorcycle should without being too much. I've got 18,000 miles on this system now and am quite happy. (OBTW, this combo was what my dealer recommended.) Hope this is some help....sorry it's not more.

I have the Akra full race system and quality and workmanship is top shelf! It provides a more linear power delivery and the "power band" at 5K RPM is gone. It sounds good too and is not as loud as some of the other systems that I've heard.

I spoke to a BMW dealer about exhausts and his reply was the reason that BMW approve Akrapovic is due to the correct back pressure it provides. Some of the other systems are too free flowing and may cause lean mixtures at some stages. Apparently the ECU cannot compensate enough and you may run into issues.

Will I buy Akrapovic again? Yes.

Cheers

...with the cat-less original headers, and the Laser I've got, the system as free flow as you can imagine...

...no problem with a lean mixture though...
...you can smell that by miles...

...maybe the RB helps a lot here...


...and power delivery is as linear as a straight line...
...never would have thought it would be that good...
...from less than 4000 RPM up to 8000+ RPM there is torque...

Bob Hancock / Skoeter:

Bob thanks for the information!!!! BTW, my research has found that by doing what you have done, header replacement only is the most cost effect way to go and provides 90% of the HP gains. Also, at this point in my riding, I also prefer less noise/don’t draw attention/minimize potential fix it tickets of keeping stock cans – therefore my interest in just doing the headers.

Skoeter your beautiful full Akro system is the best way to go and for me I wish that Akro would offer their header system separate (however, I have found that one has to purchase their whole system if ya what the headers, which is where the real power/improvement is).

Anyway, in the next week or so I’ll make my mind up, be it Remus, Laser or BOS and pull the trigger.
Thanks again:

Bob has it right. The true gains were in the header. This was discussed long ago many times when the bike was just coming out. The rest is all aesthetic (a word I can write, but not say). However, I think even the header gains were only about 4% without doing a search.

[Skoeter]

You are correct about the headers being the restriction. You can go the way RoLoo has gone and remove the cat.

BTW this is Akra's claim by means of a dyno print. It is apparently rwhp. Note the increase in torque. Now that is "real world" usable power that is shown. I do not use the high rpm range most of the time on the road, only when on the track.

During the last track day at Kyalami, they did a noise test at 4,000rpm and got a 93dB. Limit for the day was 110dB. So, it is really not too loud.

The custom design for the R12S by Akrapovic also make the rear end of the bike look slimmer. The dual can layout is in my opinion a bit dated.

...well...
...I also love the music from the eighties & nineties...

...and I also wear a 501...



...now you know why I love the dual cans...
