hey everyone, this is my first time to repack an exhaust. i have looked up how to do everything and I'm stuck in one spot. all the rivets are filled and popped out, but now i am trying to hit the end cap side and the motor side of the muffler with no prevail. i know its going to be a pain since the carbon build up and heat, but do any of you know which side should pop off first? this is the hmf sport series muffler. thanks any help appreciated
