The Arrow Race-Tech exhaust features a uniquely shaped muffler that is unlike anything else available. This innovative shape design allows the Arrow Race Tech exhaust to have reduced dimensions compared to traditional shaped exhausts. The exhaust also features a significant weight reduction without having to compromise internal volume which would increase the exhaust note. The internals of the exhaust are made of stainless steel and assembly is completed by TIG welding on special jigs. The rear end cap or gas outlet is designed to optimize gas flow.
Arrow's exhaust technologies are a direct result of their research and development through racing in MotoGP, Moto2, Moto3, World Super Bike and countless Enduro Rallies.

I bought this for my 2021 500EXC-F. It replaced the stock muffler with a billet end cap. The weight savings over the stock muffler is noticeable. The sound is awesome, not too loud but more aggressive than the muffler it replaced. Not nearly as loud as a 450sxf. Also, there was a noticeable increase in torque. 4th gear clutch ups are effortless now. I really wish Arrow made a titanium header to match instead of the stainless, hopefully in the near future.
