I put one of these on my GTS 300. It is good for what I wanted but I'm not sure everyone would like it.
This is really not a performance exhaust. It isn't a straight through design, and the pipe isn't wider (in fact, the opening at the end is a little smaller); it uses the usual reflection, absorption and restriction techniques to muffle sound.
This isn't a loud exhaust either. You can hear it at idle, but it's only a hair louder than stock. It just sounds a little lower pitched or "throatier." At speed, I can't hear it at all.
I didn't notice any performance difference after installing it. But I've already made a number of performance tweeks. There is only so much you can do with a single cylinder 300, IMHO.
Anyway, it installs easy. I had a hell of a time removing the existing torx bolts. I stripped them and had to drill them out. Had it not been for that, this would have been a 10-15 min job.
Best part about this exhaust is it looks cool, and sounds cool when you start up or stop at a traffic light. It also wasn't expensive $310 at Scooterpartsco.com, and it was easy to install.
