Yea the quad is still in the works. But the heat shield works really well.The pipe can be red hot and you can touch the heat shield by hand its barely warm. Its sound bad(pg).It has alot more rev then other pipes. I still working out bug on my quad but im getting to run better.I thinking about get the jug ported soon.Or going to a bigger sleeve with porting and a pro head cut for the right squish.When you get it keep us update and make some videos of your quad.
