Will these mufflers fit my Harley?
These slip-ons are compatible with all 1995-2016 Harley-Davidson Touring models with stock dual head pipes, including the Road Glide, Street Glide, Electra Glide, Road King, and more. As long as your ride was released within those years and hasn’t been modded significantly, these slip-ons should fit seamlessly with no modifications needed.
How loud are the Boneshaker slip-ons compared to stock mufflers?
Boneshakers are substantially louder than stock Harley Twin Cam aftermarket exhaust mufflers. They amplify the signature tone of your Harley, creating an aggressive, deep, and full-bodied tone you can feel while you ride.
While they pack a punch, they offer a more moderate volume compared to our louder options like the Bullies and Jackhammers. For maximum volume, those are worth a look!
Are these slip-ons street legal?
Boneshakers use a cat-back system that won’t alter your bike’s stock catalytic converter, ensuring that they’re compliant with emissions requirements in the vast majority of locations. We recommend checking your local sound level regulations, as laws vary by state.
Do I need to remap or tune my bike after installing them?
Because the stock catalytic converter remains unchanged, remapping isn’t necessary after installing these aftermarket mufflers for Harley-Davidson Touring models. If you’re using this Harley Twin Cam aftermarket exhaust muffler with a new header or air intake system, you may want to retune your ride to optimize fuel mixture and overall performance.
What tools do I need for installation?
We design our slip-ons to be user-friendly, even for riders who don’t have a ton of mechanical experience. They use your bike’s existing mounting points. Most of our customers complete the installation in under an hour using basic hand tools like a torque and socket wrench. You may want to have penetrating oil on hand if your ride has older hardware.
What materials are the Boneshaker mufflers made from?
We use top-quality steel to ensure that our Harley Twin Cam aftermarket exhaust mufflers will last for the long haul. Our polished chrome and black Cerakote finishes are both extremely durable, and Cerakote is especially resistant to corrosion and heat.
Can I install these myself, or should I take them to a shop?
Even if you don’t usually tinker with your ride, you should be able to install these slip-ons yourself. No cutting or welding is needed, and the slip-on design means you don’t need to modify your stock exhaust system. If you’re hesitant or adding other customizations, it never hurts to take your bike to a pro.
Will these slip-ons affect my bike’s performance?
Our Boneshaker aftermarket mufflers for Harley-Davidson Touring models are primarily designed to amplify sound. However, our Harley Twin Cam aftermarket exhaust mufflers do reduce backpressure. Many riders enjoy a slight performance boost, including a better throttle response, improved exhaust flow, and mild torque and horsepower gains.
For a more significant boost in torque and horsepower, we recommend pairing Boneshakers with a full exhaust system and tuner.
Are there any warranty protections?
Yes, we take care of our customers. Our slip-ons are backed by a Limited Lifetime Warranty on material defects and a one-year warranty that covers the finish. Order with confidence, knowing you're investing in a top-quality product with recourse available on the off chance there’s an issue.
Can I choose different end cap styles or finishes?
Yes, the body of our Boneshaker Harley Twin Cam aftermarket exhaust mufflers comes in your choice of polished chrome or black Cerakote ceramic. The billet end caps are available in the same finishes, so you can mix or match the look as desired.
