USE AND CARE
It is important to have your exhaust system repacked approximately every 5,000 miles.
It is important to know that different materials and components may require different cleaning methods. In general, clean your system when it is cold to prevent spots from burning into the surface, and avoid any harsh chemicals or cleaning products which are acidic.
While some M4 exhaust products are “replacement parts” under CARB regulations, and some may not exceed the federal EPA noise standard, in general, M4’s products are designed and intended for closed course competition use only. It is the customer’s responsibility to know their local and federal laws. M4 Products will not be responsible for any incidental or consequential damages, contingent or otherwise, including expenses for injury arising directly or indirectly from the use of exhaust system products.
If damage occurs to any item(s) in transit, it is the responsibility of the carrier. Damage claims of this nature must be made with the carrier.
