I finally got to the point where my original exhaust had reached the end of it's usefulness. I had been reluctant all along to change the exhaust because of the price. To me $199 is a lot of money (especially when the Scooter was only $588 new) too pay for something that doesn't really make that huge of a performance difference. Luckily I came across this set-up at ScrappydogScooters.com www.scrappydogscooters.com/139QMB_50cc_Performance.html
For only $129.95 they were quite a bit cheaper than anybody else. First of all I had an excellent experience with scrappydogscooters.com. I ordered this on a Monday and had it at my doorstep in Florida on Wednesday. I had JB Welded my third and final hole on my old one..
The build quality was good on the new exhaust, the welds looked pretty good...
There was a little slag left over on the flange that I had to grind off.....
But no big deal, I figured I might have to do something like that with such cheap prices. I was really afraid that the brackets would not be in the correct position. But, I was lucky it pretty much bolted right up. The top bracket had some space between it and the case when I got it bolted up....
Nothing a few stainless flat washers couldn't handle.
Other than that it was a quick easy bolt-on conversion. It looks great...
I haven't really noticed that much of a performance gain over my stock pipe with 2 holes drilled in the end. BUT, It sounds really good!! It has a much more throatier, deeper tone to it now. I have to do a plug check today, too see if I have leaned it out too much. But it runs really good and I don't think the jetting has changed much from my stock opened up exhaust. The good thing about stainless is it should last virtually forever so I won't have to do this again. Not that it was a terrible job, only took about an hour to do, and I had to run to the hardware store twice!!

I go by ear and I would not be comfortable with it revving much higher than it is now. Once in a while would be fine but not every time I take off from a light.
