A quick before and after of the BWM F900XR Stock Exhaust and the MIVV X-M1 Titanium exhaust. DB Killer is in so this is road legal. It's not much louder but it has a more aggressive tone, sounds much nicer through the rev range and now gives a nice pop and crackle when coming off throttle. Biggest difference is the weight. It's nearly 5kg lighter and you can feel that difference when you come of the stand.
