I used the Promoto spark arrestor and the quiet insert, worked great and I didn't even have to rejet.

The Dr. D seems to be cheaper then the pro moto. Is there anything wrong with the Dr. D? Is there advantages or disadvantages to either one?

I've sold both, they are very similar, so similar that I would think the performance would be identical.

PMB with no problems. Even asked them for extra bolts so I could tap out my own and they sent them with the kit. :thumbsup:
