big gun exhaust
Big Gun Exhaust is located in Corona CA and is legendary for high quality, affordable exhaust systems for street and off-road motorcycles, ATVs, and UTVs. They offer EVO and ECO series exhaust systems for more major UTVs than any other exhaust manufacturer. Most major exhaust manufacturers build systems for the RZR, Commander, and Rhino, but if you’re the proud owner of a darker UTV like the Gator or Redline, it can be a little tricky to find a suitable system.
Big Gun makes slip-on and full exhaust systems and is one of the few manufacturers to offer restoration services. For $60-100 you can polish up your old system and replace minor parts for a truly “like new” look. Most companies like to sell you another product once the original wears out or fails completely. Big Gun believes that your systems should last as long as your vehicle.
Big Gun also makes a proprietary “Rev Box” for Arctic Cat, Polaris and Kawasaki UTV models. These convenient and easy to install boxes increase your rev limit by approximately 1000 RPM depending on your machine model. The vehicle’s timing curve is reprogrammed to increase horsepower and torque with just a simple installation.
The TFI Box is the second electronics for most major UTVs offered by Big Gun. It essentially acts as a carburetor despite the use of fuel injection by your vehicle’s engine. Essentially, it uses load-based technology to control the demand on your engine and provide a fuel solution to achieve optimal performance. Plugs into the factory wiring harness so no additional rewiring or modification is necessary.
Big Gun also offers a full line of Sparkys, cores, gaskets, inserts, end caps, and springs to help customize the look and tone of your exhaust systems. The short insert, nicknamed the “Vortex”, is a 2″ spark arrester that will reduce the noise level of your Big Gun Exhaust by 4-5 decibels. The Vortex 2 is a full 5″ length that will reduce the tone of your exhaust to 96-98 decibels. It is the quietest insert available, but is not recommended for Teryx 750, Rhino 660, or other high compression engines.
Packaging is another way to reduce sound levels without significantly affecting performance. The repack kit is available in 15″ and 17″ loose-fill high-temperature material. If you want to pack it up and forget about it, consider the Dura-pack packing kit. It is guaranteed to last 50 hours and while it reduces heat, it still allows for a full, throaty exhaust tone.
