Prime Race Parts Titanium Turbo Discharge Flange – 4"

Prime Race Parts – Lightweight Titanium Turbocharger Fabrication Flange

Build a lightweight, high-quality turbo exhaust system with the Prime Race Parts 4" Titanium Turbo Discharge Flange, designed for custom motorsport fabrication where strength, heat resistance and minimum weight are priorities.

Manufactured from titanium, this flange provides a dedicated connection point between a compatible turbocharger discharge and 4-inch titanium exhaust or downpipe system. It is ideal for fabricators building premium turbo systems where conventional stainless-steel components would add unnecessary weight.

The flange allows the turbocharger outlet to transition directly into large-diameter titanium pipework, creating a clean and professional foundation for downpipes, dump pipes and custom exhaust systems.

Why Use a Titanium Turbo Flange?

The area immediately after the turbocharger experiences extreme exhaust temperature, vibration and thermal cycling.

Using a purpose-built titanium flange allows the fabricator to maintain titanium construction from the turbocharger discharge into the remainder of the exhaust system, helping reduce overall system weight while providing the heat and corrosion resistance required in demanding race applications.

It also eliminates the need to transition between dissimilar fabrication materials at the beginning of the downpipe.

Ideal for 4" Titanium Downpipes

A 4-inch discharge system is commonly used on serious high-horsepower turbo combinations where exhaust flow and reduced restriction are priorities.

The Prime Race Parts Titanium Turbo Discharge Flange provides the starting point for combining the turbocharger with:

• Prime Race Parts 4" titanium straight tube
• 4" titanium 45° bends
• 4" titanium 90° bends
• 4" titanium flex bellows
• 4" titanium V-band assemblies
• Titanium O2 sensor bungs
• Titanium mufflers and exhaust-control components

Together, these components allow a complete lightweight titanium turbo exhaust system to be fabricated using matching materials.

Fabrication Notes

Correct turbocharger flange alignment is essential to prevent unnecessary stress being transferred into the turbine housing.

The downpipe should be supported independently rather than allowing the complete exhaust-system weight to hang from the turbocharger.

Professional TIG welding with appropriate shielding and back-purging is recommended for titanium fabrication. All welding surfaces should be thoroughly cleaned before assembly to prevent contamination.

Important Fitment Notes

Turbocharger discharge flange designs vary between turbocharger manufacturers and turbine-housing configurations.

Always confirm that the flange profile and mounting arrangement are compatible with your specific turbocharger before welding or fabrication.

The 4" specification refers to the intended discharge / pipework size.
