Frequently Asked Questions

Do these slip-ons fit my 2006-2011 Dyna?

Yes — these bolt directly onto stock Dyna headers. Will not fit pre-2006 or 2012+ models.

Will I need to rejet or retune?

Slip-on mufflers alone typically do not require remapping, but a tuner can optimize fuel and air for better performance.

Are they street legal?

Check local noise ordinances in your area — Cobra slip-ons produce a classic aggressive tone that may exceed some state limits.
