Just purchased a pristine ZX-14 exhaust manifold off fleabay, I plan to keep the bike single exhaust for awhile as I want my girls to have a side they can get off the bike with no exhaust. I already have a stainless muffler on the bike and was wondering if anyone has had any luck shimming the Ninja manifold and using the slip on they already have? I know there is a difference in the OD-ID from the manifold to the stock Connie exhaust but was hoping not to have to go out and purchase another slip-on just to use the manifold. Eventual plans are to install a full dual system and likely purchase a pair of matching pipes that will fit correctly but that is a future project and for now I'm on a budget so I'm trying to go cheap. Has anyone done this with success?
