Before installing a new muffler, align the ends of the exhaust pipe that were attached to the old device. Attach the new muffler to the same hangers on which the old one was fixed. Insert the muffler into the ends of the exhaust pipe. Tighten all fasteners and clamps. To install the nozzle, choose the size of the nozzle taking into account the parameters of the ends of the muffler, the shape of the nozzle and the shape of the cutout of the car bumper. Install the muffler after cleaning the exhaust pipe. Apply automotive grease to the inlet of the muffler tip. After that, install the nozzle on the exhaust pipe of the car, using clamps or welding.
