Motorcycle enthusiasts sometimes drill a hole in their exhaust pipe as a way of making the bike louder and giving it a bit more power due to extra airflow. A clogged exhaust can prevent a vehicle from operating. Drilling the exhaust also may temporarily restore function so you can get the car or bike to a repair shop. Drilling holes in an exhaust can be done in seconds.

Check your state laws about drilling holes in your exhaust since the action may violate auto emission laws. While drilling the hole to get to the mechanic is unlikely to create much problem, you should be aware of what the law is before deciding to proceed. You can check search engines online or contact your local police department and ask over the phone.
Attach a 1.5-inch drill bit to your drill with a long extension. You'll need the drill to fit about 10 inches down the exhaust pipe.
Insert the drill down the exhaust pipe until you feel it connect with the baffle plug at the end.
Drill slowly to let the bit dig in and get a grasp on the metal. Increase speed and pressure to then drill a hole through the exhaust pipe.
Start the vehicle to force the metal piece you just drilled out of the exhaust pipe.
Add additional holes as needed.
