2-into-1 Systems

What is a 2-into-1 Exhaust System

Cobra's 2-into-1 exhaust systems are just that. The two head pipes flow into a special collector that mates with a single muffler body. The collector is covered with a unique heat shield that keeps the junction area looking clean and neat.

What is the benefit of a 2-into-1 system?

For the most part, a 2-into-1 motorcycle exhaust system will produce more power than the stock system or most 2-into-2 systems because of improved exhaust scavenging.

Additional Details

Each system uses single-piece heat shields on the head pipes and each is finished off with a machined aluminum tip.

    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.
