American exhausts for powersports

Big Gun is an American brand specialising in exhausts for ATVs, UTVs and motorcycles for off-road and street use. The exhausts are developed for specific models, so they fit without major modification and give a noticeable improvement in the engine’s character. The range is divided into series by use, with solutions for everything from work machines and leisure riding to competition. The focus is on tough materials, good fitment and a sound that suits the purpose.

Big Gun’s key products

The EVO U series (Utility) is intended for ATVs and UTVs used for work and trail riding, and comes as both slip-on and full system. The EVO R series is aimed at racing and sport riding, where performance and low weight are the focus, while the ECO series is a more affordable alternative. Many exhausts are made from stainless steel, and several models have a removable spark arrestor or sound insert. Full systems may require fuel adjustment. See each product for model fitment.

Frequently asked questions

Should I choose a slip-on or a full Big Gun system?

A slip-on replaces only the muffler and is easy to install. A full system also replaces the head pipe and usually gives the biggest difference in performance and weight. The choice depends on your budget and your goals for the machine.

Do I need to adjust fuelling after fitting a Big Gun exhaust?

With a slip-on it is often not necessary, but with a full system adjusting the fuelling, for example with a fuel controller, is often recommended. Check the description on each product for recommendations for your model.
