As you may recall, I had recently purchased on the hot new "Clubman" style exhausts made by BGM. (get yours here). I thought it would be a straight up fit, but alas, I was mistaken. The exhaust header would not clear the fins on my cylinder. (photos here)
With that problem, it seemed only brute force would be my solution. So I got out the trusty Dremel tool and got to grinding. I roughly marked where I thought the header was hitting the cylinder, and cut away. As you can see in the photo above, I got the small bit off that was interfering. Then I cinched up the header. You can clearly see how beefy and huge it is. Nice! As an added bonus, I should be able to get the pipe and u-bend off without taking off the motor tin. I like it.
Here is the pipe on the scooter. As you can see, it looks totally stock. I can report that, at idle, it is surprisingly quiet. It is almost as quiet as a stock scooter. However, once you get on the throttle for any amount, it gets loud quickly. No big shock, I mean, it is a performance exhaust. I can also say that this scooter is crazy fast with this pipe on it. I still have to do some jetting work, but it just feels like it wants to rip through every gear. It is very very quick. (note, the motor is a mildly street tuned 175 with a mikuni flat slide)
