Fuel consumption drop on Aftermark exhaust?
I was thinking about getting an aftermarket exhaust for my Bear 650 and had a few questions.
Would replacing just the exhaust slip-on be enough to get a noticeably better sound, or would I need to go for a full-system exhaust with a decat?
Also, does fuel efficiency decrease in both cases?
I actually tried removing the stock exhaust completely and went for a 30 km ride. The fuel efficiency dropped significantly to around 10–12 km/l.
Is that expected when running without the stock exhaust, or could there be another reason for such a big drop?
