Cobra is the only one of the two that offers a full system from front to back, I have owned for about a month one, however it isn't in my possession yet (thanks Western Honda), I think that it will be worth the wait. I do know in the world of high performance atv's "DG's crap, Cobra's crap, so pick your pile". Kaysen
