Designed specifically for utility ATV’s, sport utility ATV’s and Side x Sides, the EVO U series is not for the faint of heart when it comes to raw power and sound.

**This system is not ARB / CARB compliant and cannot be sold in the state of California**
Big Gun exhaust systems are warranted against manufacturing defects for material and workmanship for 1 year from the date of purchase from Big Gun or from any authorized Big Gun dealer, distributor, or exporter. During the warranty period, the warranty is limited to the repair or replacement of defective products. The warranty shall be void if the exhaust has been mounted on a vehicle and run, or it is determined that any alleged defect is the result of misuse, neglect, abuse, or modification of the product. There is no warranty for how the exhaust sounds (i.e. too loud), normal wear and tear of products, or for any damage that may have come about from a crash, or from improper maintenance of the muffler and/or packing. There is no warranty on exhaust with regard to any form of discoloration or bluing which are caused by tuning characteristics (i.e. cam timing, carburetor jetting, over heating due to lack of packing and incorrect fuel/air mixture) and is not caused by a defect in manufacturing.
Proper tuning is a must! Now that you’re getting a performance exhaust system, be sure to tune your vehicle in order to maintain the Big Gun warranty. If you have a carbureted vehicle, proper jetting is required. If you have a fuel injected vehicle, the use of a fuel controller / programmer is required. Without proper tuning, your motor and exhaust will run hotter than normal due to running “lean,” a condition that adds unneeded wear on your exhaust system and motor.
All Big Gun Exhaust mufflers come with the highest quality high-temperature fiberglass packing inside. Repacking your muffler every 15 – 20 hours of ride/drive time is required. Failure to properly check and repack your muffler as required will void the warranty. A muffler with little to no packing will have nowhere to dissipate the heat of the exhaust. Signs of packing deterioration can include: increase in overall sound, discoloration of the muffler and end tip, peeling and/or discolored decals/badges, a slight echoing and loose rivets or screws.
