COMPLIANCE WITH EMISSIONS REGULATIONS
This website primarily lists special performance parts, many of which are designed for racing, competition, and off-highway use only. Customers are advised that vehicles equipped with such parts should not be operated on public roads.
Mountune LLC offers such parts only for track or off-highway or competitive performance use. U.S. and Canadian laws and regulations prohibit removal of or tampering with components installed on production vehicles to meet emission requirements applicable to vehicles manufactured for use on public roads.
It is the responsibility of the customer to ensure that their modified vehicle is operated in a manner that complies with applicable laws. Parts with the notation "California Executive Order: 50 States Legal" in the product description have been determined by the California Air Resources Board (CARB) not to have an adverse effect on emissions when installed and used properly. Under CARB and EPA policy, such parts may be installed in vehicles driven on public roads and highways.
Parts that do not have a CARB Executive Order (EO) in the product description are intended to be installed in vehicles used solely for racing, competition, and off-highway purposes. Such parts may not be installed in vehicles driven on public roads and highways.
While many Mountune Performance Parts have no application for vehicles driven on public highways, Mountune recognizes a special responsibility regarding environmental concerns and continues to develop, analyze and test additional engine and powertrain parts with the goal of making them “50 States Street Legal.”
Mountune's vision is to provide products that meet all of our customers’ performance part needs while remaining environmentally responsible.
