Since installing the Vance & Hines exhaust I've had an exhaust leak that i cannot get rid of. It leaks on the right side where the muffler meets the head pipe. If you look in the pic below, the leak is coming out of the two slots just in front of the clamp. It almost seems like the exhaust air is getting under the gasket inside the pipes and then exiting through these slots. Anyone else had this issue?
