Does exhaust packing affect performance?
Similarly, it is asked, what can I use for exhaust packing?
Most come from the mfgr packed with fiberglass mat wrapped around a screen core. Many bike shops carry repacking material or you can just use regular old fiberglass mat from the local hardware store.
Subsequently, one may also ask, how often should you repack your muffler?
It can happen quickly, too. We know mechanics who recommend new muffler packing after every 10 hours of riding. That could be once a month, or even more frequently.
For over 30 years, stainless steel wool has been widely by OEM”s to prevent blow out of fiberglass packing materials and/or to enhance the sound of the exhaust system with a deep exhaust tone. Mufflers packed with stainless steel wool will last up to 4 to 5 times longer than by using fiberglass alone.
