LOL "no mods.."

never change the exhaust on a modern car with computer controlled ignition without adjusting the timing. Of course _you_ can't adjust the timing! Now the engine is running ignition advance that's way too high for the new exhaust. I bet if you tear down that engine there will be pits all over the pistons and heads from the detonation.
