Hey, I just got my set of V&H SideShots, already installed the air cleaner and FuelPak. I removed the stock pipes w/ no prob. Having a really hard time getting the new pipes to fit. Tried a few times w/ the heat shields on like the directions called for. No Luck. Took the heat shields off, still no luck. I'm getting really tired of scratching coating off my engine. Anybody done this? any tips?
