The manifold is made from Billet 6061-T6 aircraft grade aluminum.  The end tanks start off at over 50lbs of material for each side and end up about 3.8lbs that's a lot of chips!  Like all of our products these manifolds are completely made in the USA.
 
The manifold features integrated Port Injection, and Meth or nitrous bungs.  This means when you purchase the manifold there is no need to add a fueling spacer between the engine and the manifold.  The Injectors are now relocated to the topside, making them easier to service if needed.  In addition to adding more fuel, we have designed the manifold to accept a larger throttle body for those extreme horsepower cars! 
 
Injectors, meth nozzles and Nitrous nozzles are all sold separately.
