[QUOTE="Catmonkey, post: 16096701, member: 124025"] We could sit here and guess all day, but until you datalog the car and send it to your tuner, it will all be idle speculation. An exhaust leak will introduce air in the exhaust and make the O2 sensor's think it's running lean, which in turn will cause the PCM to add more fuel. Long tubes are also a lot further back from the OEM locations and may take longer to heat up. There are some things that need to be done in the tune for long tubes. [/QUOTE]
