Item specifics

TB45 Turbo Manifold (Tuned Length)

Turbo Manifold – T3 or T4 Flange 

Please advise which flange you require (T3 or T4) when placing your order.

Radius Fabrications offers a custom-built turbo manifold designed to suit a variety of turbocharger setups. Whether you are upgrading, fabricating a new system, or replacing an existing manifold, our Australian-made manifolds are engineered to provide reliable fitment, strong welds, and optimal flow.

Each manifold is fully jig-built, TIG welded by our qualified fabricators, and finished with CNC-machined mounting surfaces to ensure a perfect fit against the cylinder head and turbo flange.

If you choose to add a wastegate flange, you will be required to send us your wastegate flange before production begins.
Radius does not sell wastegates or wastegate flanges — we only weld the flange you supply.

Any modification to a standard Radius Fabrications manifold (including customer-supplied wastegate additions) voids the Radius warranty.
