How To Clean Exhaust Tips with WD40 or with household items

Exhaust tips are usually metal piping that protrudes from the exhaust system and is used to deflect some of the engine’s unburned hydrocarbons that normally exist as part of the exhaust gases. They can get dirty and clogged with carbon, which causes a restriction in airflow. If you don’t clean them out regularly, it will result in poor fuel efficiency and lower horsepower.

They also have a secondary function as an aesthetic enhancement besides the deep sounding performance. However, as they are subjected to heat and grease, they can become blackened in appearance over time.
