So its getting pretty warm out now and going slow in the trees my exhaust is getting pretty hot and heating the gas in my tank and causing it to run like crap. It is a 2015 viper mtx with a Yamaha acc. mpi 190 kit. Runs great but this has happened to me on two trips now. Any one else have this happen? I don't have vents yet and still have the quiet muffler on it. Think ceramic coating the header would help? And I am getting the loud muffler just haven't yet.
