If you already have a stage 1 set, you only need the upper manifold.

Stage 3 manifold requires a riser, it will not fit on the car without a riser

*Please Note*  We are not accepting core exchange orders at this time. This is temporary and due to the lack of cores in stock. We will offer core exchange in the future, when we have more cores in stock. The only order option right now, is to send yours in. You may purchase a core set elsewhere and send it in to us, if you can not have your car down. All orders made with the “send mine in” option will be given top priority. 

 

Our stage 3 manifolds take your power to a new level!

Our stage 3 manifolds offer the same mid-range torque and horsepower gains as the stage 1 does, but also adds peak horsepower too. Dyno tests have shown 8-12whp gain up top.

For our stage 3 port jobs, we cut the upper manifold open so that we can gain full access to the runners, then we weld it back together. We remove the lip from the mouth of the runner, expanding the opening by 2mm or more. We remove the pillars on the divider and we remove some of the obstructions that prevent airflow from properly entering 2 of the ports.

No one else does this port work, we’re the first and only.

How long does it take?

Stage 3 porting will take 1 month and you will be scheduled. It could take up to 2 months before your order ships, so please be aware of this time delay!

Upgrade from stage 1

If you already have a stage 1 manifold set from us, you only need the upper manifold to make it a stage 3.

A riser is required!

Because we eliminate several reliefs in the casting, your upper will no longer bolt up. You will need a riser to add the clearance.
