The exhaust on a vehicle is a means for the engine system to release and expel the resultant gasses from the combustion within in a safe and unobtrusive way. While this is an integral task in the process of running a vehicle, the noise created by some exhaust systems is loud to the point of unbearable. There is a simple device called an exhaust silencer that you can use to minimize and muffle the unpleasant sounds.
Wipe out the inside of the exhaust pipe with a cleaning cloth dipped in water. This will remove carbon deposits and dirt that have built up in your exhaust.
Push the silencer as far as it will go into the exhaust pipe with the metal tab aligned along the top of the exhaust opening.
Make a mark with marker through the small hole in the tab of the silencer. Pull the silencer out of the exhaust.
Drill through the mark on the inside of the exhaust with a power drill, through the interior layer of the exhaust. Do not drill through the exterior layer.
Push the silencer back into the exhaust pipe and insert the included screw into the tab and the hole in the pipe. Use a screwdriver to tighten the screw until it holds firmly against the silencer.
