Well you can't sell it because you don't have the red R (via a donation to the site). I would suggest getting one off ebay, there are always stock systems being sold on their. Check it out, and you will be able to get a full system for pretty cheap.
Yes, I know, this should more then likely be in the "For Sale" forums, however, I tried to post there and it said,"You do not have access to this", maybe i'm doing something wrong, anyway..
I'm gonna try to sell my bike, however, I need a new exhaust, cause the guy before me had a kink in it when he layed it down, and I heated the kink up with a welder and used impact sockets with an extension and hammer to hammer the diameter back out almost to specs, but it is mis-aligned and whatnot, and looks really ugly, and is an eye-sore if I want to sell it. I was wondering if anyone had maybe a FULL stock exhaust they might be willing to let go for cheap? It would be greatly appreciated ..
