Big Gun 09-16 Polaris Sportsman 850 / 16-23 Sportsman 850 HL EVO U Full System

The 304 stainless steel mid-pipe and head pipe construction on this Big Gun EVO U full system is a solid starting point for anyone looking to upgrade their Polaris Sportsman 850's exhaust. This isn't just about a deeper, throatier sound; it's about unlocking more power and torque from your utility ATV. The restrictive stock exhaust can really hold back an engine, and this system is built to let it breathe easier.

You'll notice the oval-shaped aluminum muffler, coated in a high-temperature black thermal finish. It's designed to provide maximum clearance, which is crucial on an ATV where space is often tight. The muffler bracket is TIG welded for strength, and it comes with a removable screen-type spark arrestor, which is important for trail riding. Big Gun also includes their Vortex Quiet Insert, giving you an option to manage the sound level if needed, though this system is definitely not for those seeking a quiet ride. The black powder-coated stainless steel end tip gives it a clean, finished look.

This full system is handmade in the USA and is significantly lighter than the stock setup, which can make a noticeable difference in handling and overall performance. If you're looking to dump that tinny-sounding stock exhaust for something with a more aggressive, powerful tone and a substantial increase in horsepower and torque, this Big Gun EVO U system is a well-built option. Please note that this exhaust is not CARB approved and cannot be shipped to California.
