How easy is it to install?

Our Harley Davidson Softail slip-on mufflers are true “slip-ons.” Loosen stock clamps, swap cans, align, and torque to spec. Most riders finish in under an hour with basic hand tools – no tune required for stock head pipes.

Work on a cool bike, use anti-seize on hardware, and re-check fasteners after the first ride.

Will installing the Boneshaker Harley Softail slip-on exhaust void my Harley’s warranty?

Installed correctly, it shouldn’t. This is a cat-back system, so emissions catalysts stay untouched. Because we don’t alter the engine’s internal components, dealers typically view slip-ons as a cosmetic/sound upgrade. Always keep your receipt and follow torque specs to avoid pushback.

How loud are your slip-on mufflers for Harley Davidson Softails?

Louder than stock – absolutely. You’ll hear a deeper idle, a stronger mid-range bark, and a satisfying roll-off. Not glass-pack harsh. We tune for presence over drone so highway miles stay enjoyable. Still, every city’s different; know your local noise rules.

Check noise and local rules:

If your area posts limits or “quiet hours,” do a quick look-up before the install. It’s the same advice we give buddies at the shop, and it makes for less hassle later:

• Many municipalities reference dB thresholds at specific RPMs
• Some events or communities enforce time-of-day restrictions.
• When in doubt, ride respectfully, and you’ll rarely have issues using Harley Davidson Softail slip-on mufflers.

Can I customize the look?

Yes. These Harley Softail slip-on exhausts come in chrome or black ceramic, and the billet end caps swap in minutes:

• End caps: polished or black
• Finish: mirror chrome or heat-tough black ceramic
• Vibe: Choose between classic brightwork and stealthy blackout – your call

Does the Boneshaker slip-on improve performance?

Our flow path reduces backpressure compared to many stock cans, which may sharpen throttle and mid-range feel. Exact gains depend on bike condition and setup, but riders usually report crisper response. If you add intake or a tune later, the Boneshakers slip-on mufflers for Harley Davidson Softails are ready to play nice.

What kind of warranty is included?

You’re covered by a limited lifetime warranty on material defects. The finish is covered for one year.

Keep your proof of purchase and install per the instructions. If you ever need help, reach out to get in touch with real techs with real answers. We ride these too, and we’ve got your back.
