Akrapovic installation with pics

Today the brown-suited Santa Claus brought my long awaited Akrapovic exhaust. From the moment I laid eyes on the R12R last summer, I felt that the stock can really looks out of place on such a nice back left side, especially with the single swing arm; I knew it had to go. 10 days ago I plopped down $770 to Kneedraggers.com and this afternoon, the Akrapovic exhaust showed up on my doorstep.

Right off the bat lemme tell you that the sound is terrific! It's a nice deep bass at idle, which unfortunately is all I got to hear it at since the weather here in SATX today ranged from drizzly to cats-and-dogs to who-the-heck-is-dumping-buckets-of-water-on-my-house?

Installation was easy, straightforward and fun. I had no problem doing the swapout and I'm mechanically retarded as all get out.

Anyway, here's what the bike looked like before the surgery. That's the Akrapovic in the styrofoam down there on the ground.

The Akrapovic package included a detailed instruction guide, a replacement 13mm nut and washer since the stock can has the nut built into the attachment flange, a small tube of copper never-bind lubricant, a "street legal" certificate (whatever the hell that is), and enough Akrapovic stickers to let everyone know where you dropped your last paycheck. In my zeal to get the new can attached, I failed to photograph any of this stuff but it was all there, I assure you.

My first surprise was how light the Akrapovic can is. It's light enough that my 5-year old could heft it, as seen here:

Note that I removed the Akrapovic sticker from the side of the can. That took about ten minutes of rubbing the sticky goo off with my fingers since the Akrapovic boys don't recommend citrus-based cleaners to be used on the can (probably to keep the sticker from coming off...oh well). Anyway I don't want my R to turn into a NASCAR machine with commercial endorsements everywhere, so I pulled the sticker off. Notably, the sole exception is the "Bitte ein Bit" sticker on the side of my bike, but that's more tradition for me than actual endorsement of Bitburger beer - I can't stand the stuff nor do I believe that alcoholic beverages and motorcycles should have anything to do with each other, but I digress....BTT.

Removal of the stock can was very easy, requiring only a 15mm wrench for the exhaust clamp and a #45 torx bit for the attachment flange. Both the attachment flange screw and the exhaust clamp are reused with the Akrapovic. I started the bike up without the can just to see how it sounds - not too loud as others have reported. Here's a pic of the R with the exhaust removed.

AJ didn't like the heavy stock can as you can see:

Next you have to coat the exhaust clamp with Akrapovik's copper never-bind lubricant for whatever reason. 15 years in the military got me in the "don't question why, just execute" mindset when it comes to mechanical things of which I have no understanding, so I plopped the goop where the instructions said to:
Image

Finally it was just a reverse process of getting the new Akrapovic can back on the bike. It was a very snug fit, but not difficult at all. The fitting really sealed up very smoothly when I tightened up the exhaust clamp - I guess that was what the never-bind lube was for. Total job time from start to finish was about 30 minutes, but that was with stopping to take photos. Here's the final result:

And some side-by-side comparisons of the two cans next to each other. The Akrapovic is really a work of art, and is very complimentary to the lines of our beautiful bikes.

And as a final note I have one nearly-mint condition (only 200 miles) stainless stock can for sale cheap.

Looks fantastic, Matt. I hope to be doing this same swap within a few weeks.

How much louder is it? Or does it rumble a little more?? No remapping or tuning involved?
Thanks :?:

Rokin,

It's not too much louder, just a heck of a lot more bass (at least with the silencer inserts in). It's a deeper, fuller sound than before, but again, not too much louder.

No remap is necessary.

I wish you hadn't bought that thing, because now I might have to buy one!

My big concern would be loudness. The stock muffler is too quiet, but I wouldn't want to go too far the other way just for the weight savings. I recently rode a K1300S, which was outfitted with the full Akrapovic kit, for a whopping $1900. It had the restrictor plate in, and it sounded very nice. The owner of the bike said he could hardly tell the difference in sound between that and the stock can. I have a recording of it. It's quite pleasant.

Please let us know your impressions once you get the thing out on the road.

I have the same muffler, and even with the baffles removed, it's far from obnoxious. If you search on "R1200R Akrapovic" in YouTube you'll find a few examples. A couple do sound pretty loud, but I think that's more to do with the location than the pipe. The video headed "Pot Akra sur BMW R1200R" is the one that sold it for me and I reckon it's a pretty accurate sound recording.
