it will work with your stock manifolds or shorty headers. So you should be good

The one that says headers is prolly a slightly different product number and is made to fit long tube headers go with the one that says fit to stock and pay attention to the product number

If it says O/R mid pipe then it fits stock manifolds if it says SHORTY O/R mid pipe its for long tubes

had the mac on stock manifolds and worked fine. just make sure you have a new manifold flange gasket. don't use the crappy one mac sends
