I can't find one on Ebay and I missed a few auctions on the whole exhaust (big waste anyway). Please contact me if you have one (stock or not, it doesn't really matter...). In a previous post there was a suggestion on how to make the uncorked exhaust a bit less noisy (alluminum tube glued inside) but I can't find it, if it is not too much trouble, please repost the length of the tube and how much it should extend past the end of the exhaust. THANKS!!!
