Our Two Cents
Periodically changing the packing material in slip on and full system exhausts is necessary. Neglecting to do so can lead to canister/muffler damage.
Two brothers doesn’t give specifics on exhaust repacking intervals unfortunately. I have been told “unofficially” that it is good to change the packing material every 3,000 to 5,000 miles.
