Popping and farting with a decat pipe
« on: April 13, 2019, 11:50:09 AM »
I'm on my second S1000R and although the first one did the above too, i only ever had a standard set up on that one. The latest one has a decat pipe and Akra slip on.

It pops and farts all the time, in any revs, any gear, and especially when i change gear using the qs. I presume it is running lean, does it cause any long term engine damage by running the bike this way?

Does it do it in rain mode? If not, it's completely normal, BMW call it "thrust acoustics".

If you want to get rid of it then install some block off plates. I have some driven block off plates but have yet to install them, I like the pops and crackle of the exhaust.

I tested this yesterday on my R and XR, and the over-run pops definitely diminish when in Road mode compared to Dynamic mode.

Hi everyone, I have a2018 s1000r with Akpovrovic headers and in rain mode there are minimal pops however I am not a fan of the false popping caused by "thrust acoustics" as is turned off in rain mode I am wondering if it is possible to turn it off in the other modes
