I have this pipe it's been sitting on my mantle since April. I used it for 4-5 rides and it doesn't have a scratch or dent on it.
I'm looking for 600$ obo for the system.
Save a couple pounds, gain around 2 horses and free revving from your YZF.
System is almost 1500$ after tax if you got it from a dealership, or around 1000$ if you get it from ebay
Pictures of it on the bike, and finally where it has sat since April.
