Will these slip‑ons fit my Harley Touring bike?
These Jackhammer slip-ons are specifically designed and optimized for 2017 and up Harley-Davidson Touring models that have stock dual head pipes. Our M8 Touring exhaust mufflers use the bike’s stock mounting points and don't require extra adapter kits or brackets.
Do I need to modify my emissions or install any extra parts?
These Milwaukee 8 slip-on mufflers use a cat-back design that keeps the original emissions system fully intact. You won’t need to tamper with the stock emissions, catalysts, and controls or use aftermarket headers or any extra parts. They’re 100% street-legal. Just bolt them to your original head pipes and experience the roar!
How loud are the Jackhammer slip‑ons? Are they too loud for daily use?
These aftermarket M8 Touring exhaust mufflers are definitely loud, but they have a deep, throaty rumble that’s not harsh and easy on your ears. Jackhammers are louder than Boneshakers and tamer than Bullies, offering an excellent balance. The megaphone structure and proprietary baffle design bring the roar without overwhelming your eardrums in traffic or on long adventures.
What is involved in the installation process? Can I do it at home?
The bolt-on installation is simple and straightforward, even if you’re not typically a tinkerer. Because Jackhammers use the stock hardware and mounting points, the DIY upgrade can usually be performed with basic hand tools in under an hour. No welding or cutting required.
Do I need to retune my ECU or adjust fuel mapping after installation?
Although our Jackhammer M8 Touring exhaust mufflers are engineered to be compatible with the original fuel maps, you may wish to get your ECU retuned to optimize throttle response and overall performance. You can also maximize power and eliminate the possibility of backfire or popping with a professional dyno tune or basic plug-and-play fuel management module.
How will these slip‑ons affect my bike’s performance and backpressure?
These Milwaukee 8 slip-on mufflers have a unique megaphone-shaped exhaust flow and proprietary baffle design that deliver a responsive throttle feel without affecting low-end torque. You can expect a more open, clean tone and sharper acceleration off the line, without compromising the backpressure required to keep your engine operating smoothly long-term.
Are these slip‑ons street‑legal and compliant with emissions regulations?
Yes, because our Jackhammer M8 Touring exhaust mufflers use a cat-back system, they don’t alter the stock catalytic converters and sensors. This means they’re fully compliant with CARB and EPA emissions standards. Make some noise without getting on the law’s bad side!
What maintenance do these mufflers require over time?
For basic care, occasionally clean the outer finish with mild soap and water to maintain that stunning showroom shine and prevent corrosion. The mounting clamps and hardware should be inspected every few thousand miles. If low maintenance is a top priority, we recommend the ultra-durable black Cerakote finish, as it’s highly resistant to fading and scratches.
Will installing this M8 Touring exhaust muffler void my Harley’s warranty?
Because they bolt onto stock mounting points without requiring welding or cutting, Harley-Davidson dealerships generally accept our Jackhammers. And, they don’t alter your ride’s engine internals or emissions system.
Even though you shouldn’t run into any warranty issues, for your own peace of mind, you should always double-check the dealer’s warranty policies before installing aftermarket components.
What warranty and customer support come with these slip‑ons?
Our Jackhammer Milwaukee 8 slip-on mufflers are backed by a limited lifetime warranty that covers manufacturing defects, as well as a one-year warranty on the finish. We’re known for our responsive customer service, so don’t hesitate to reach out with questions about your M8 Touring exhaust mufflers.
