dillegm 5 Posted April 19, 2017 Kolpin Stealth Exhaust 2.0 with Heat Shield - 53570 https://www.amazon.com/dp/B001Q4UC52/ref=cm_sw_r_cp_api_Hr39ybJAH7PS4 I've been considering purchasing one of these for my Cforce400. I've read many reviews, good and bad. Anyone here have any feedback you can offer? It seems it does well on 300cc to 500cc machines but not so well on larger displacement machines. Thats what I gathered from 100+ reviews between Ebay, Amazon and a few other sites.
