Treadstone Performance Engineering, Inc releases its new line up of stainless steel cast turbo manifolds offering uncompromising performance and unparalleled durability.
Treadstone manifolds are cast using the latest in turbocharger-manifold technology using state of the art CAD based techniques. They benefit from an exclusive investment casting method utilizing bulletproof 347 stainless steel. The high thermal inertia and excellent heat retention of cast 347 stainless steel provides the turbocharger with as much thermal energy as possible. This effect raises the overall efficiency of the system and produces results superior to tubular/welded manifolds. Furthermore, 347 stainless steel is virtually impenetrable to rust and other forms of corrosion and will stay looking beautifull for years to come. No more rusting looking turbo manifolds!
This manifolds is an exact replica of our cast iron manifold we have been selling for years!
