Default Loud Pop after turnning at wot question...

Basically I was turning right on a green that was about to turn red so I hit the gas while in 2nd gear. In the middle of my maneuver I heard and felt a loud popping sound. Almost like someone threw a large rock at the car. It seemed like maybe one of my springs popped off or something but I do not see anything abnormal at all. The car dives perfectly fine. Maybe it was a backfire? It happened once b4 too actually about 2 months ago. Any ideas???

I suppose it was a back fire...yeah I do not have all the breathing mods you have. All I have it the Stillen Cat Back and pop charger. If those alone produce LOUD hard hitting backfire's then I'll just lmao next time it happens.

"Engine backfire
Backfire in an automobile engine typically results from various malfunctions related to the air to fuel ratio. Usually, backfiring occurs in carbureted engines that are running lean where the air fuel mixture has insufficient fuel. ("Running lean" is typically a sign of mal-adjusted carburetors or fuel injection where there is not enough fuel for the amount of air). Afterfire, however, occurs in engines that have an exhaust leak or unburnt fuel in a decatted exhaust system. When a driver shifts up and lets off the gas, the engine has a moment of running rich or with insufficient oxygen. This causes an incomplete burn which causes the fumes to explode in the exhaust system. The leak itself is the most dangerous aspect. Without it, the mixture would cool enough not to explode. A fuel injected engine may backfire if an intake leak is present (causing the engine to run rich), or a fuel injection component such as an air-flow sensor is defective."
