Our studs

 

We offer Ti6Al4V titanium alloy and Inconel 718 exhaust studs.

Our titanium studs are made from heat-treated Ti6Al4V alloy, which is much stronger than mild steel employed by stock exhaust studs, but 45% lighter. They are also impervious to corrosion and heat resistant; hence they will not rust and look like new indefinitely, and will be easily removed from the cylinder head when needed without breaking, a common issue with the stock studs.

Our Inconel studs are made from Inconel 718, a gamma double prime heat-strengthened Inconel Alloy, a family of austenitic nickel-chromium-based superalloys. Inconel 718 is an oxidation-corrosion resistant material with excellent tensile, fatigue and creep-rupture strengths. It is well suited for operations in extreme environments subjected to pressure and heat. Inconel retains strength over a huge temperature range, attractive for very high temperature applications where steel would succumb to creep as a result of thermally induced crystal vacancies. Under extreme use, the steel/stainless-steel studs can expand enough to loosen off and eventually break; which might be especially true in racing or high-performance street applications, and turbocharged engines such as in the GT2, GT2RS, GT3, and GT3RS Porsche 911s.
