Developed 30 years ago, initially on the Sierra Cosworth, our equal lenght, oversize primary headers ensure an optimum flow of the exhaust gas coming out from each of the 4 cilynders, down to the inlet port of the Turbo, increasing the spooling efficiency and the perfomance by a great amount.
During the R&D process, the goal of creating a smooth-bend design was relatively easy for us to achieve; however we anticipated that by using the conventional steel tubing, the resistence and the durability would become a concern.
Thanks to our contacts in the tubing Industry, we were able to source a special grade of steel, the 310S, an alloy developed specifically for the exhaust headers of the F1 cars of the Turbo era.
Used in our std. wall thickness of 1.5mm, this superior material resists the quick thermal expansions and the most brutal, repeated heat cycles like no other steel alloy does.
Up to date, the 310S steel tubing is used almost exclusively in the performance exhaust industry, only by very few manufacturers.
The weight saving over the cast-iron, stock manifold is massive.
After all these years, we are proud to still offer this Supersprint headers in its original form.
Alongside our manifolds, we also have the Supersprint turbo-back, stainless exhaust available.
