Just noticed on our way back from the Boo Run in Jefferson that my SEII slip ons sounded pretty good. After I put them on last year I was hoping they would have sounded a bit louder. Do you believe in Seasoning??? Just a thought
:hmmm:

This tends to be the case with many exhaust systems, including stock. They can sound better with age. Typically the exhaust note becomes slightly fuller, bigger and louder... with a nicer tone. Preceding said, some systems can become flatter and more blatty, especially if the muffler has packing and needs to be re-packed. This tends to be true with some aftermarket systems on sportbikes.

Packing burns out. Had a *** bike, at 5k, was so noticebile I pulled over.

Oh yeah they get louder with use. No doubt about it.
