RE: Akrapovic - 3

Currently I have a Remus Hexacone w/ the baffle out. I'm currently running a short windscreen that in the high position the wind hits me right in the chin. I went for a spirited ride on backroads on Sunday. With earplugs in and music playing at full volume in my Schuberth C4 (integrated speakers) I could still easily hear my exhaust. When I first mounted the Remus, I ran the bike with the baffle in for about 15 minutes, and it was only slightly louder than stock, which will be perfect for long rides. Do my ears just work better than y'all's or do you want a super loud bike? With my current set-up, The bike is just a tick louder at idle and neighborhood speeds than I'd like. If I had feelings, I'd almost feel like a dickhead in neighborhoods. Just curious about what folks are looking for with their exhaust volume.

I also have a Remus exhaust on my '16 RS, but run with the insert in. I like the deeper tone and slightly louder exhaust note. To me it's a decent compromise. But even with the baffle out, you can short shift through a neighborhood and not be annoying to most people. Even my old 2V Ducati, with what amounts to 2 marginally muffled pipes, can pull that off. But at highway or higher speeds it is still quieter than the RS. Mainly because on the Ducati, your helmet is in clean air. A rarity on the Beemer. But ultimately, because their exhaust note has so much character, any twin cylinder bike deserves something more than a stock muffler.

I bought a set of Acro titanium headers from another forum member. They are scheduled for delivery on the 1st. I suspect I'll want to reinstall the baffle after installing the headers, because at that point I expect to be obnoxiously loud if the baffle is out. I'll update once everything is put together.

Just an update! Full Exhaust is installed and I've ridden with baffle out and in. The baffle really kills a lot of dB to the rider's ears, and I'm assuming everyone else. Baffle out with headers and no cat was a bit too loud and droney if I did any highway riding. Never obnoxious to my ears, but just constant exhaust noise that was easily heard by me even with music playing in my helmet and wind noise. It's so quick and easy to remove/install the baffle I may pull it out for a particularly sporting group ride I occasionally do, but I'll likely leave the baffle in the rest of the time. It was just a tick or two louder than I wanted with the baffle out if I was riding through a neighborhood.

I expect I'll be adding a powercommander eventually, as I suspect the bike is running a bit leaner than ideal. I don't expect that will change any sounds the bike makes, except maybe some more snap, crackle, and pops on decel and downshifts.

Guys in the first post it says that the Akrapovic will fit most LC bikes
I have a brand new Arka ive just fitted to my 2017 1200RT LE but am trading it for a 2018 1200RS SE will the exhaust fit from the RT to the RS ?? I hope it does
Thanks

Installed the Akrapovic can and cat-delete header on my brand new 1250RS and I had MAXBMW performance-tune the bike.
Significant difference in performance, from an already strong performing bike. One thing...you can actually tell when the cam shifts, now.
Have not seen actual numbers from MAX, but I do know fuel consumption went from ~44mpg to ~38mpg.
The sound is definitely better...not loud and obnoxious like the Termi's on my Ducati...but a nice mellow tone. Throatier than stock.
I'd upload a video but the file size is to large and I have no way to compress it.

Slightly off piste but what panniers are those, they look amazing

If I’m not mistaken they are the BMW ones in Black. Which do look very good. (For panniers, but they hide the lovely Akro!)

Question for Jay K.. When you had MaxBmw do the tune did you see or get a read out of the dyno numbers? How’s the gas mileage been. I’m seriously thinking headers, I called Akrapovic and asked if a tune was needed when adding headers. They said no tune needed. I’m not sure about that. Any added info you or anyone else have would much be appreciated

@Oldbiker, I'm runing Akra headers with a Remus can, and I have not done a tune. I only added a Servo-buddy to avoid the ECU code. I've had no issues. From my research, which I can't easily share, the BMW ECU will make adjustments to the increased flow as well as for things like altitude, temperature, and air density, etc. I saw that the piggy-back systems, like Power-Commander, do not make any adjustments. My inclination is that I don't get close to using the full capabilities of my bike, so it wasn't worth the money for the tune/piggy-back anyways, and all indicators are that wear and tear on the motor are not affected. I didn't need to upgrade the exhaust, for me it only makes more and more pleasant noises, but I like to spend money on my bike sometimes.

I’ve just mounted the Akro Ti can to my 2020 RS and am considering their de-catted headers. Is the Servo-buddy necessary for anything other than clearing the error code? I already have fault codes from my LED turn signals (NewRage Cycles) so another error message might not bother me unless there are other considerations. When I performed the same surgery (full Remus kit) on my R9T, there were no error codes at all, just a lot better exhaust note.

Leave the servo in place and disconnect cables, seal cable hole with a little sealant to prevent water ingress. This will work fine until such a time you decide to dump servo and add a buddy to fool onboard computer.

Thanks Ady. I’ll do just that next rainy season when I have a service due anyway.

I have fitted a new 🦂 Scorpion Redpower .
I run it with the baffle out .
Kinds great not to loud.
