So I got some free time this evening and have started the process of making my ninjette worthy of the Franken-Ninjette name.
I'm about 3/4 of the way done fabricating a 2:1 exhaust out of the stock on my '06 and an exhaust off of a '10 Ninjette. All I have left is the welding which I'll be be doing tomorrow, so I'll have some pics up by evening.
Overall the process is going much more smoothly than I had anticipated. I've put about 5 hours into it so far, and like I said I'm more than half way there. Not expecting a whole lot performing wise, but it definitely looks better.
