Dual exhaust with the Flo-masters will increase the horse power and give it a great sound. Just don't take it to Midas. Fine a good hot rod type shop that does this kind of mod. You don't want the biggest pipe made to hook up to your ride, without doing major mods. Stock exhaust manifolds are fine. The ram horn style exhaust deliver lots of flo for the stock motor. Ask the installer to add a cross section the the system to equal the back pressure and flo. This should be a great modifacation for for the Elky. Good luck.
