Circuit Werks Borg Warner S400 Turbo Exhaust Flange Kit - 4" Stainless Steel Clamp & Flange

If you're building or upgrading a turbo setup for a Borg Warner S400, this flange and clamp kit from Circuit Werks is exactly what you need.

It includes a 4-inch inner diameter stainless steel flange and a matching heavy-duty clamp.

Everything's made from stainless steel, so it'll hold up to the heat and last.

It's a performance/custom part, meaning it's meant for fabricators or guys putting together their own exhaust systems.

No bolt holes—you weld the flange on.

60-day warranty, just in case.

Whether you're piecing together a kit or repairing an existing setup, this kit gives you solid components.

Get that exhaust hooked up right and spool that turbo!
