The Big Gun Re-packing Kit is available in 15" and 17" and is composed of loose fill 'high temp' type packing material. This race-bred packing is designed to reduce decibels, while keeping the horsepower of the exhaust at its maximum. This can be used in all Big Gun Exhaust Systems.
It's great easy installation I didn't notice a power gain but the main reason I bought it was cause I failed sound test (96 db) but It didn't lower the db as much as I had hoped... It went from 97.5 to 94.1 although It was in a white bros aluminum pro not a big gun but super easy to install and the thing I loved the most about it was... I wasn't all itchy after like normal re pack kits
Great product has been repackaged so cleverly and is therefore easy to install
I would recommend it.
Highly recommended this packing. Easiest install I have ever done. The packing has an adhesive strip that holds itself tight to the inner barrel of the muffler, making it a sinch to slide the packing back into the muffler housing.
this stuff worked awsome very easy to install i put it in my stock 06 yz450f pipe.
