My 2006 Civic Is Backfiring After Cold air Intake And Exhaust! Why?

I have a fujita F5 cold air intake and a magnaflow exhaust. after i installed the exhaust i can hear backfiring.

"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."


That's the defenition. I am running regular gas.

What cna I do to fix this? Any help will be greatly appreciated! Thanks in advance!
