I always believed the alien exhaust was just some stupid looking expensive exhaust system made by some cheap no name company. Last weekend I was proved wrong. I saw a raptor with the full system DMC up close, tell you the truth, that pipe barks, I mean you couldn't sneak up on a deaf man with this thing, but it's not just good for attracting attention and making your quad sound throatier than ever, it has gobs of performance. Right now I have a pure polaris slip on, i'm waiting for that DMC so bad too, or the trinity I can't make up my mind which to get but I really want a full system, none of this slip on crap.
