The Big Gun Evo Utility Series was designed to deliver raw horsepower and torque gains throughout the RPM range for ATVs and UTVs. Made from 0.049" stainless steel tubing and an aluminum muffler canister, the Big Gun Utility exhaust system is much lighter than stock units. The sleek muffler design also allows for maximum clearance to avoid your exhaust from hitting the rear brake caliper.

All EVO Series pipes come in stainless steel, with a CNC bracket, Race Tools packing, and spark arrestor screen. No other pipe on the market will come with these accessories included.

  • Much lighter than stock exhaust.
  • Massive horsepower and torque gains.
  • Hand TIG welded 0.049" 304 stainless steel mid pipe construction with a brushed finish.
  • Sleek silencer design provides maximum clearance and prevents silencer from hitting the brake caliper.
  • Flat black, ceramic-coated, oval-shaped 6061 T-6 aluminum muffler housing; thermal barrier keeps heat from melting fenders.
  • Slip-fit design prevents cracking exhaust systems by allowing movement between mid pipe and silencer due to sub-frame movement.
  • Aluminum end tip with thermal disbursement coating which dissipates exhaust heat.
  • Vortex Quiet Inserts included; 94 - 96dB stainless steel internal baffle core.
  • U.S.F.S.-approved screen-type removable spark arrestor is included.
  • TIG-welded, reinforced muffler bracket.
  • High-performance Race Tools silencer packing with stainless steel screen.
  • Handmade in the U.S.A.
  • One-year manufacturer's warranty.

Ease of Installation

Better luck next time

had to cut the exhaust pipe to fit the grizzly. the exhaust is extremely loud. I installed the spark arrestor and within a few hours i blew a hole in it. where the pipe meets the exhaust there is a major exhaust leak. all in all not happy with the pipe but what can i do. i do not recommend this exhaust.

I bout a slip-on big gun evo exhaust for my 2007 660 rhino an was told by dealer that no rejetting was needed so do I need to rejet?

Jetting is dependent on each situation. There's a couple factors you'll want to take into consideration, like elevation and temperature. I'm not sure if you have other mods on your particular Rhino as well. Usually, it's going to be necessary to get a jetting kit when you change out the exhaust. This is going to help get the most out of your performance add ons as well as make the UTV run properly.

Will I need to buy a efi programmer for a fuel injected atv?
For a Rincon 680.

For a slip on normally you really wouldn't need it. It should automatically adjust for the most part, but it's always recommended to get a programmer once you start messing with the intake/exhaust system.

What is the proper jetting it talkes about i have a 2001 Honda Foreman trx450 ES?
MotoSport Staff

Since jetting specs vary from place to place and from what you have already done to your bike, You would need to install the exhaust and see how it responds, then take it to a local shop for tuning.

Without having to do any modifications you will be stuck with utility type exhaust systems.
