D-I-Y Steel Exhaust Manifold Flanges

If your goal is to fabricate a set of custom exhaust manifolds for your 1984-89 Nissan 300ZX & 300ZX Turbo, these Do It Yourself Exhaust Manifold Flanges from PastPower Innovations should make your life easier during the process.

Our exhaust manifold flanges allow you to put to use a proven flange design to create an exhaust header or turbo manifold system to best meet your power goals and needs. With our multi-flange kits, you will not have to cut flanges in an unsightly manner like with one-piece flanges. Our flanges are made of super beefy 1/2″ steel to ensure that you have no warpage or sealing issues when joining the flanges to your exhaust tubing.

In addition, the bolt/stud holes on each flange have been redesigned for M10 hardware – standard on VG33 cylinder heads and and a common modification for VG30 cylinder heads.

Our Nissan VG30/VG33 Exhaust Manifold Flange Kit comes with

• Six (6) individual exhaust flanges
