An exhaust leak shouldn't cause much of a loss of horsepower but maybe a couple because it'* disrupting the flow in the system. Most likly cause would be the MAF. I've read of cases where descreening the MAF causing a lean condition. As a matter of fact with the exchaust I'm running some people recommend removing the screen to reduce the popping in the exhaust at start up when the car is running richer.
