Exhaust Flap Delete

Exhaust flaps are a common feature in modern cars that allow for a quieter exhaust note during normal driving conditions while opening up for a louder, more aggressive sound under harder acceleration. However, some car enthusiasts prefer a louder exhaust note all the time and may consider an exhaust flap delete as a modification. In this article, we will explore how an exhaust flap delete works, the benefits it provides, and how Inverness Tuning can help improve your car’s performance.

Exhaust Flap Delete: How It Works

Exhaust flaps work by directing the flow of exhaust gases through either a closed or open pathway, depending on the position of the flap. The flap is typically controlled by a vacuum or electric actuator, which opens or closes the flap based on engine speed, load, and other factors.

An exhaust flap delete involves removing the flap and welding the exhaust pipe in the open position. This modification ensures that the exhaust gases flow through an unrestricted path, resulting in a louder exhaust note.

Benefits of an Exhaust Flap Delete

Aside from the obvious benefit of a louder exhaust note, an exhaust flap delete can also have a positive impact on the performance of your car. By removing the flap, the exhaust gases flow through a more direct path, reducing backpressure and improving exhaust flow. This can result in improved horsepower and torque, as well as a more responsive throttle.
