How do Jackhammer slip-ons compare to other exhausts in terms of sound?
Our Jackhammer Harley-Davidson Touring pipes provide an ideal balance of tone and volume. They’re more extreme than Boneshakers, but not quite as thunderous as Bullies. Jackhammers are undeniably loud, but not ear-piercing, delivering an aggressive, deep-throated rumble without excessive drone or harshness.
Are these slip-on mufflers easy to install?
Absolutely. Our Harley Evolution and Twin Cam slip-on exhaust mufflers use the original factory mounting system, so you can bolt them on directly without needing to alter your bike’s emissions system. Even if you don’t have a ton of mechanical experience, you should be able to finish the installation in less than an hour using basic tools.
What materials are these slip-ons made from?
This Harley Evo and Twin Cam slip-on exhaust muffler is built from premium steel that you can depend on to withstand regular road wear and extreme exhaust temperatures. They come in classic, sleek chrome, or choose the black Cerakote ceramic coating for the highest level of heat resistance and durability.
Do Jackhammer slip-ons affect performance?
Although their major selling point is their incredible sound, Jackhammers can boost exhaust flow in comparison to the restrictive stock mufflers. You may experience slightly better power delivery and smoother throttle response, especially if you use them alongside a high-flow air intake and tune the bike accordingly.
Will these slip-on exhausts pass emissions tests?
Because our Harley-Davidson Touring pipes have a cat-back design, they don’t remove or modify your bike’s catalytic converters, keeping the original emissions system intact. Therefore, you shouldn’t run into any compliance problems. With that said, volume regulations do vary by location, so check your local exhaust noise laws before ordering.
How do I choose between the chrome and black Cerakote finish?
It depends on your style preference and riding conditions. Chrome has that iconic, high-shine look that fits the classic Harley style. The matte black Cerakote ceramic coating delivers a stealthier aesthetic with higher durability and heat resistance. Either way, you can’t go wrong.
Do these mufflers require tuning after installation?
Most riders who use our Harley Evolution and Twin Cam slip-on exhaust mufflers won’t need to tune their bikes because the stock head pipes and catalytic converters don’t need to be modified or removed.
However, if you decide to pair them with a high-flow air intake or other aftermarket components, you may want to use a fuel tuner to optimize the throttle response and engine performance.
What kind of warranty do Jackhammers come with?
This aftermarket Harley Evo and Twin Cam slip-on exhaust muffler is backed by a Limited Lifetime Warranty that covers material defects. The finish is covered by a 1-Year Warranty. Order with confidence, knowing your product is built to last.
