Thanks to @HyperStraaaada for the great deal on the SC Project exhaust. Was hoping to fit it at the weekend, but..... the 'boss' has taken it off me until my Birthday in late August Grounds for divorce in my opinion.
Tell her you need time to fit it, and that fitting it isn't the pleasing part and is more like hard work. Say that once fit, you just won't use the bike until the big day. Give her the key to establish trust... Then break that trust by whipping out the spare key and going out for a blast.
It's the only way Not only because I found it a right arse to put back in/take off - the bolt ended up inside the carbon cap a few times, and the baffle slid to the bottom at least once!
