Build a stronger, more reliable turbo setup with this cast stainless steel external wastegate merge, designed for welding onto a turbo manifold collector or runner pipe. The curved profile extends past the weld joint to create a strong lap joint, helping reduce the chance of cracking or failure in high heat, high boost applications.

Manufactured from cast 316 stainless steel, this merge offers excellent corrosion resistance and long service life, while also being compatible with 304 stainless steel systems. It is designed to suit a 2-1/2 inch diameter straight pipe and can be installed anywhere along the outside radius of a 90 degree bend on a 2.5 inch outside diameter tube, giving fabricators more flexibility during custom turbo manifold construction.

The flange side is made to accept your preferred wastegate flange, providing compatibility with 44mm, 45mm and 50mm external wastegates. This makes it a versatile choice for performance turbocharger setups where strength, fitment and heat resistance are essential.
