Will the Bullies slip-on mufflers fit my Harley Touring model?
These slip-ons are compatible with all 2017 and newer Harley-Davidson Touring models with stock dual Milwaukee 8 header pipes. Installation is simple, as they use the existing mounting points on your Harley M8 Touring exhaust system. No modifications, special tools, or mechanical experience are required.
How loud are Bullies compared to the stock mufflers?
Bullies are our loudest slip-ons and some of the most thunderous slip-ons on the market. To say they’re tremendously louder than stock mufflers would be a massive understatement! The rumbling tone is deep and aggressive, dialing the natural sound of your engine up to 11. Rest assured, if you crave volume, Bullies deliver in spades.
Do I need to retune my bike after installing these mufflers?
No, these slip-ons are a cat-back system, meaning they keep your emissions parts fully intact and integrate seamlessly into your Harley M8 Touring exhaust setup. As long as you’re keeping your factory air intake and headers, retuning is unnecessary.
Are these mufflers street legal?
Because our Bullies use a cat-back system, they don’t alter your ride’s stock catalytic converters or remove any emissions components. While these slip-ons definitely crank up the volume, you shouldn’t have to worry about getting on the bad side of the law in most areas. Of course, you should always check local regulations on sound levels to be sure.
What materials and finishes are available?
Bullies are crafted from hard-wearing steel and come in two finishes to complement your Milwaukee 8 header pipes: sleek black ceramic Cerakote or classic chrome. Cerakote boosts the long-term durability of your Harley M8 Touring exhaust system, thanks to its exceptional resistance to corrosion and heat.
Can I install these myself, or will I need a mechanic?
Because Bullies slip-ons use the same mounting points and styles as the original factory setup, most riders can install them in under an hour using basic hand tools. Even if you don’t have a lot of mechanical knowledge, you shouldn’t run into any issues.
Will these mufflers improve my bike’s performance?
Although they’re most famous for their incredible sound, Bullies are engineered to reduce exhaust backpressure, which may give your torque and horsepower a slight boost, enhance your Harley M8 Touring exhaust flow, improve throttle response, and optimize the overall feel of your ride.
Do the mufflers come with end caps, or do I need to buy them separately?
Yes, we include billet end caps with each set of Bullies. With your choice of either black Cerakote or polished chrome, you can give your exhaust setup a custom look with no additional components required.
How much do the mufflers weigh?
Bullies weigh roughly 14 pounds, which is what you can expect from most aftermarket slip-ons. The balanced design is optimized for stability and performance on your Milwaukee 8 header pipes, so don’t worry about your bike’s handling or feel being compromised.
What kind of warranty do these Harley M8 Touring exhaust mufflers have?
Order with confidence, knowing our Bullies are fully backed by a Limited Lifetime warranty that covers material defects. The chrome or black Cerakote finish also includes a one-year warranty for added peace of mind.
