looking to buy 07 f800st
I am contemplating buying a 13k 07 with aftermarket exhaust. My question is will the oem fuel computerism handle an aftermarket exhaust.
It'll be fine with an aftermarket exhaust on it. All it'll do is make some more noise without something like a power commander though. If you want to realize any power gains you'd have to get a power commander or whatever works on Beemers.
I own a 2007 BMW F800st with a Scorpion carbon fiber muffler and it sounds great. You should have no trouble with the fuel mapping but be aware that you may have to drive the bike around for a few miles just to get the fuel/air/backpressure to adjust from the computer. When I took the bike in for its 18k maintenance, the service manager said the bike sounded great.
I've got a 2007 F800ST with a Remus aftermarket exhaust... no problems at all.
