All S1 R / Tarmac Mufflers Repack Kits

Two Brothers Racing’s unique muffler packing is a crucial performance part. When fresh, it allows your top-level exhaust system
to deliver power efficiently while producing the best custom sound from your machine. New packing also ensures your custom
exhaust system lasts for years. Every TBR muffler is hand packed with our high quality damping material at our factory, and you
can have the same, new-system results every time you service your muffler. Our complete Repack Kits include everything you
need to restore your Street, MX, or ATV muffler to factory-fresh performance levels. We recommend replacing the packing after
every 10 hours of use for offroad or 000 miles for road applications. Also available is the M2R removal tool for a quick on-bike
repack, not necessary but definately makes the job easier
