Inexpensive. Durable. Bolt-on. Those are terms everyone loves to hear when considering parts for a motorcycle. Pro Circuit Racing T-6 slip-on mufflers take it one step further with "Performance!" The aluminum canisters feature an asymmetrical design for increased packing volume, along with a removable spark arrestor approved by the USFS. Precision TIG-welding and a stainless steel midpipe and end cap contribute to the silencer's strength. The T-6s won't pass FIM sound requirements for pro racing in the USA or Europe, but they're a great exhaust option for off-road bikers on a small budget. Bolt one onto your stock headpipe and hit the trails with renewed giddy-up!
