i've got two of these, they kick ****. Hint for you though, if it's in good nick shine it up and get some snaps on the bike, and stick it on Ebay- if you don't clear £200 I'd be astonished. Whole system's titanium, it doesn't get blingier than that! If I didn't already have a spare I'd have it off you...
These come with the Northwind stamp of approval

Take 3 inches off the end can and they sound superb as well. Good power gain when set up right, and the lightest full-can exhaust system ever made for the SV.
