I have an extra trinity pipe I might be willing to sell. I picked it and the bigger dg carb up in a package deal. I was thinking of using it on an lt80 build that is underway, but I'm just putting it together to sell it. Most folks don't want to pay for the performance parts on a kids quad.
I have one on my daughters bike that I found for $150. It really woke up her bike along with the stuff jack did.
