The Keleo exhaust is included, I do not have the flex exhaust, ignition wires or original manual. The instructions can be downloade from Horizon's site. The engine is new, no fuel or mounting. I have priced it accordingly without the missing items. If a buyer is looking for a matching numbers Corvette, this is not for you. It is perfect for a 1/5th scale Cub, and the Keleo fits right in front of the firewall. PayPal only, I will split the shipping cost for lower 48 only.
