im not gonna lie this thing has some power, im sure it wouldnt take much to get it to eat some hills up lol. the exhaust came off my best friends quad, he is doing a full build right now and going with a Dasa so i snatched it, it had a stock one on it. Yes it has a GT thunder rear link. I like the way it sets but it would just look alot better setting with that with a different front end set-up.
