As long as it's the right one for your car iy should bolt right up. You might need o2 extensions for the front sensors(I did with my BBK). A new passenger side exhaust flange gasket isn't a bad idea either depending on the mileage of your car. You'll either need Mil eliminators for the rear if it's an O/R pipe, unless you get your chip re-programmed. Other than that you should be all set.
