About Big Gun Exhaust
Founded in 1997 by Mike Young, Jr. — a three-time AMA National Four-Stroke Champion — Big Gun Exhaust was born from real-world racing experience. Young channeled his championship-winning knowledge into building exhaust systems engineered specifically for motocross and sport ATV competition. What started as a focused performance brand grew steadily to cover Side-by-Side (UTV) and street bike markets as well. In 2010, the brand underwent a significant restructure that consolidated research, development, manufacturing, and testing operations, further sharpening its focus on quality and innovation.
Today, Big Gun stands as one of the leading powersports exhaust manufacturers in the United States. All Big Gun products are made in the USA using cutting-edge production techniques and materials selected for durability and performance. The brand's reputation is built on its ECO, EVO, and EXO product lines — full four-stroke exhaust systems featuring thick aluminum mufflers and stainless steel head pipes designed to increase horsepower, torque, and deliver a signature sound that riders recognize instantly on the track or the trail.
Exhaust Systems Built for Performance
At the heart of the Big Gun lineup are its exhaust system kits, which are the brand's flagship offering. These complete setups — headers, midpipes, and muffler combined — shed unnecessary weight compared to stock components while dramatically improving exhaust flow. Whether you ride Yamaha, Honda, Polaris, Kawasaki, or another major powersports brand, Big Gun offers fitment-specific options so you get the right system for your machine right out of the box.
For riders who want a meaningful performance upgrade without replacing the entire exhaust, Big Gun's exhaust mufflers are a popular slip-on solution. With stainless steel inner construction and lightweight aluminum canister designs, these bolt-on mufflers deliver noticeable gains in throttle response and top-end power while also offering an optional Vortex Quiet Insert for riders who need to manage sound levels. Rounding out the exhaust lineup, Big Gun also offers exhaust tail pipe tips that add a finished, purposeful look and can complement both OEM and aftermarket exhaust setups.
Fuel & Ignition Tuning to Match
An upgraded exhaust system can create a lean fuel condition if the engine's fueling isn't adjusted to match — and Big Gun addresses this head-on with its TFI (Throttle body Fuel Injection) tuning products. The brand's fuel injection electronic control units — known as the Power Box — are plug-and-play fuel controllers that remap fueling for fuel-injected ATVs, motorcycles, and Side-by-Sides in minutes, arriving pre-programmed with a balanced baseline tune for immediate usability. Complementing this, Big Gun's ignition performance modules, such as the Rev Box, allow riders to optimize ignition timing for maximum power output — particularly valuable when paired with a full exhaust system upgrade.
