what are the effects of racing with a header leak on a car? i would imagine a loss of power right? anything else, my buddy has one (05 gt) and was planning to go race at the opening of the new local track this week but his plans may have been sidelined...

i don't think it's a good idea to run it like that, i think it may lean out the vehicle because of the faulty o2 readings. not sure be i would bet its not a good idea.
