Frequently Asked Questions

Will these fit my Softail Fatboy?

Yes, if your bike is a 2007-2017 model year. Confirm your model year before ordering — 2018+ Softails use different mounting.

Do I need a tuner with these slip-ons?

Slip-ons alone may not require retuning, but a fuel-air tune can maximize the performance gains from the high-flow catalyst.

What finish options are available?

Chrome and matte black finishes are both offered.

Are these street legal?

Check your local noise ordinances. California riders should review Prop 65 warnings at www.P65Warnings.ca.gov.
