How do you want to purchase this manifold/tb combo?

Our stage 1 manifolds have offered 3.8 owners excellent mid-range performance gains, smoother acceleration and improving the results of tuning overall.

We remove all casting imperfections and make the manifolds as they were intended to be from the factory. From there we address specific areas to eliminate flow restrictions/disruptions to provide the least disruptive path for air to flow.

Various dyno testing done by our customers have resulted in gains of 10wtq and 10whp mid-range without tuning.
