Why does my exhaust pop when I let off the gas?
Why does my exhaust pop when I let off the gas? An afterburn or backfire from a vehicle’s engine on deceleration happens when unburnt fuel combusts or ignites in the exhaust pipe. The result is a loud bang or pop when you move your foot off of the gas pedal. Take note that this instance can occur in many vehicles, including trucks and motorcycles.
