Big Gun Exhaust®- FAQ Made In USA Big Gun Exhaust Authorized Dealer Product lines Warranty About us

Big Gun Exhaust® was founded in 1997 by 3-time 4-Stroke AMA National Champion Mike Young, Jr. Young knew what it took to win races. He took his knowledge of what worked on the track and used it to manufacture high performance, quality exhausts for the MX and sport ATV market, and eventual Side x Side, and Street markets. After over a decade of successful and continual growth under Young, Big Gun Exhaust was sold to a new owner. In 2010, Big Gun Exhaust changed ownership once more, undergoing a tremendous company-wide restructure in an effort to improve the Big Gun brand.

Warranty

Exhaust

Your Big Gun Exhaust system is warranted against manufacturing defects for material and workmanship for one (1) year from date of purchase from Big Gun Exhaust or from any authorized Big Gun Exhaust dealer, distributor, or exporter. During the warranty period [one (1) year], 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 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.

TFI Power Box

Your Big Gun Exhaust TFI Power Box fuel controller is warranted against manufacturing defect for material and workmanship for two (2) years from date of purchase from Big Gun Exhaust or from any authorized Big Gun Exhaust dealer, distributor, or exporter. Any modifications made to the TFI Power Box i.e. cut wires, soldered wires, excessive water damage, etc., will void the warranty in its entirety. There is no warranty for improper installation or misuse of the product (improper tuning), and Big Gun Exhaust is not liable for any potential damage caused to the engine due to improper installation or tuning.

Rev Box

Your Big Gun Exhaust Rev Box (CDI box) is warranted against manufacturing defect for material and workmanship for six (6) months from date of purchase from date of purchase from Big Gun Exhaust or from any authorized Big Gun Exhaust dealer, distributor, or exporter. Any modifications made to the Rev Box i.e. cut wires, soldered wires, excessive water damage, excessive exposure to heat, etc., will void the warranty in its entirety. There is no warranty for improper installation or abnormal use or misuse of the product, and Big Gun Exhaust is not liable for any potential damage caused to the engine due to improper installation, use, or tuning.

Tuning – Fuel Injected Vehicles

All fuel injected vehicles must have their fuel system remapped before use of any Big Gun Exhaust slip on or full system exhaust. Failure to properly remap the fuel system can/will result in major engine and exhaust malfunctions, for which Big Gun Exhaust disclaims all warranties. Big Gun Exhaust requires using a TFI Power Box or comparable fuel adjustment module for proper remapping and adjustment. Do not run a Big Gun Exhaust system until a fuel adjustment module is installed.

Jetting – Carbureted Vehicles

Improper jetting of your carburetor will void all Big Gun Exhaust warranties. For the purpose of this warranty, “improper jetting” shall mean that the jetting in the carburetor is too rich or the opposite, is too lean, causing excessive heat of which damages the structure/materials of which this exhaust is manufactured. Improper jetting can lead to exhaust failure and major engine failure.
