2018 exhaust dilemma
« on: July 03, 2018, 11:22:51 PM »
Ditched the panigali for a new S1000R and absolutely love it. What I don't love is the low DB tone from the Cat. Read lots of useful posts on here on earlier models but still no conclusive answer on fuelling after header change.
I really want a louder system but Dyno don't offer pc for my year model and I don't want to run it lean and f##k it up especially as BMW clearly stated it will invalidate warranty.
Anyone ran this gauntlet ?

After I had the headers fitted, I then found out that there was no PC offered by Dynorod due to the problem with the engine warning light.

I have been running around as it is now since November with no real detriment. Yes, the revs are a little lumpy below 3000rpm, but once you twist the right hand, it sounds and performs gorgeously.

Thanks, did you fit them yourself ? Any warranty voiding issues from your dealer ?
Spoke to Calsport yesterday, they offer a piggy back power commander "rapid evo" that learns and re fuels as you ride. Apparently when you unplug it everything goes back to normal so doesn't affect stock ecu. Not sure if anyone has tried this..
Where you based would love to hear the beast  :007:

If you don't want to screw up the fueling or bother with piggyback ecu's etc .... I really would advise giving just the Akra GP can a try first.

Similar to you, I came from a Ducati with a full SC Projects system, so the volume was turned up to 11. While the stock Akra (I have a 2017 model by the way) sounds decent, it is definitely lacking in tone and volume.

I have fitted just the can to mine for now as I don't want to ruin the fuelling and to be honest it does sound great and I now have no desire to fit headers purely for a bit more volume, and I don't want the loss in power either.

While the bike isn't as loud as my Ducati was, people still comment on how loud it is and how nice it sounds. To put it in to context, a couple of my friends have KTM 690 SMC's with open pipes and they can hear me over their bikes when I am behind and infront of them.

If you're still not happy once you've fitted and tried the can, then you haven't really lost anything as the titanium headers can easily be bought and fitted at a later date.

Hi. I have the Akra Moto GP style can on mine and the sound is superb. I thought about the full system on my 2017 bike but dont want the hassle of bad fueling etc. The can look good as well

Hi Nev,
As much as i would like to help with the sound of the bike, I am seperated from my love by 11000 miles :(

I was lazy and had the dealer fit the exhaust. Only after fitting the exhaust did they (the dealer) find out that BMW do not offer a release code for the 2017+ model - that is the ECU is locked.

I have heard of the Rapid Bike range, and there is someone on the forum that has one (he mentioned it, hence i learnt of its existance) but I would like more experienced information. I would opt for the simplist application, the Rapid Bike Easy http://www.dimsport.it/en/rapidbike/easy/.

Cheers lads, rumour is all baffling done in the cat so whipped the end can off today and went for a blast. No real change idle but sounds great at revs pops on bangs like thunder  :001:so will get the slip on ordered tomorrow. Where did everyone buy the race can from ?

I removed and sold my arrow competition evo full exhaust from my 2015 S1000R along with the power commander v and autotune and replaced it with the 2017-18 akra headers and 2017-18 akra gp can along with the rapid bike and my tuning and airbox delete.  Best thing I ever did.  The 2014-2016 headers for the akra are the same as they as for the 2014-2016.  All you need to get is the 2017-18 evotech delete system like I did.  And you can mount the 2017-18 system on the bike.  I also got the rapid bike system along with auto tune to replace the power commander and auto tune..  And got a 520 kit with a 42 rear spro kd and stock 520 front sprocket but will go up to a 46 rear sprocket instead with a red rear rear sprocket to match what i have in the rear.  Ill post what the bike looked like before and after

I bet that looks and sounds awesome, my akro GP can arrived yesterday. Fitted the new end can does make a noticable difference so happy boy for now and may still keep my warranty. Full system is the way I'll be going after warranty period ends.

Like you I had a Ducati with full termi, then a superduke with SC project can,
I did feel that my S1KR sounded loud but a bit thin. I've only put an SC Project end can on it, but it has a lot more depth, and sounds fabulous on the overrun. Highly recommended and looks so much better than the awful standard Akro. Also one advantage of the SC over the Akro Moto GP style one is that you can remove the foot hangers
