Instruction: After installing the elements of the exhaust system, it is necessary to check the absence of internal stresses in the system, as well as the presence of a sufficient distance between the elements of the system and the body. If necessary, loosen the double clamp and align the exhaust pipe and muffler so that there is sufficient clearance from the body and the fasteners are evenly loaded. Self-locking nuts must be replaced.
