I went for a fun trip last week to Glamis with my 2018 RZR Turbo, which has an Agency Choice exhaust. While riding, I noticed an exhaust leak... I found a nut and stud on the manifold had come loose. I tightened them, but the leak's still there. I'm not sure what else to check, maybe a gasket or a crack somewhere? If anyone has dealt with this or has ideas on what to look for next, I'd really appreciate the help
