If you seek to alter your motorcycle’s exhaust tone and improve its appearance without spending a fortune, a slip-on exhaust can become the most optimal solution. This type of exhaust system modification replaces just the muffler, so it is a simple upgrade that does not require remapping. You also don’t have to remove the exhaust control valve to install it. A slip-on can also increase horsepower as some muffler designs improve the flow of waste gases. This upgrade is budget-friendly and easy to perform while being effective enough. Those who race at a professional level are also looking to save weight. For MX racers, we have mufflers made as lightweight as possible while being durable, with internal constructions that ensure high flow and more power.
We perfectly understand the adventurous spirit which fuels you and makes you head out for more and more challenging rides. Our comprehensive collection of motocross and dirt bike slip-on exhausts is designed to meet the demands of every motorcyclist, including weekend off-road riders and racers alike. With our products, you’ll have that extra horsepower to push your bike a bit harder than you used to; you’ll also obtain a signature sound and look to distinguish the character of your bike.
