Just wanted to know if having a  couple wholes in my exhaust system( Cat and muffler) would effect the power of the car, im asking this because everytime i hit the gas it kinda boges out for a bit before it picks up, but still dosent have the response as it should like my 2.8 did when i slammed the pedal

holes wouldnt rob you of power...a clogged cat would....if it bogs down, odds are its a fuel issue... check your injectors/filters....could be something as simple as your gas filter....
