Detail your Performance Exhaust with TBR’s custom color bolt kits. Any of our M-series exhaust canisters can be customized with this anodized bolt upgrade. Chiseled out of pure 7075 T-6 Aluminum, our bolt kits come in custom colors to match your style. Installation tool and awesomeness included.
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.
