Stage 2 Manifold Porting (BK1 3.8)


Stage 2 Manifolds for peak performance! Includes Upper and Lower manifolds.

Please note these are scheduled and are not shipped immediately.

Financing available! Details at Checkout

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

Stage 2 manifold requires a riser, it will not fit on the car without a riser



Our Stage 2 BK1 3.8 manifolds offer the same mid-range torque as the stage 1, but improves the top end by eliminating the oddly shaped and narrow mouths of the runners. We cut the manifold in half so we have direct access to the ports to get them to the perfect shape, letting your 3.8 breath until redline!

Purchase options:
1.”Send mine in” means exactly that. You remove the part  from your car and send it to us. We port it and send it right back. Turn around time for this option is usually 1-2 days after we received your part.

2. “Core exchange” We will port and polish a used manifold and send it to you. When you receive the parts, you remove the stock set from your car and send it back to us. Turn around time for this option is based on the current stock. We do our best to keep these in stock to minimize the wait time. Further explanation of the core exchange can be found under the “info” tab.

3. “Purchase a core” means you are buying a used part from us, we will port it and send it to you. You will keep your stock set and the ported part we sent to you.
