Frequently Asked Questions

Do these require a tuner or fuel module?

Slip-ons typically do not require retuning, but a fuel-air optimizer may improve throttle response and fuel economy.

Will these fit my 2016 or older Touring?

No — these are engineered for 2017-2025 Touring models only. Older Touring bikes use different header geometry.

Are they street legal?

Yes — this configuration is 50 State EPA-legal. Always verify local noise ordinances in your area.

What's included in the box?

The pair of slip-on mufflers with all mounting hardware needed for installation onto stock headers.

What kind of sound do they produce?

The 2.25" perforated core delivers a traditional, recognizable Harley deep tone—not overly aggressive.
