Ease of installation along with some of the best prices available make Cobra slip-ons the smart choice for riders of all abilities.

Emissions Notice

The state of California considers aftermarket exhaust systems to be legal replacement parts for non-catalyst equipped motorcycles and/or if slip-on mufflers are installed downstream of the OEM catalysts.

California does not allow the use of aftermarket systems that remove original equipment catalysts, (except for racing use only) unless the Air Resources Board has issued an Executive Order for that system.

For California riders we offer Air Resources Board approved Fi2000 R ARB units. (ARB E.O. No. D-633-1). All other Fi2000 models are not legal for street use in California.
