Walton Motorsport 304 Stainless Steel Head Flange (Ports for Stubs) BMW S58 Fibre Laser Cut

As used on our very own range of manifolds plus many more custom projects, we now offer these to you for your own projects. Fibre laser cut from 10mm Thick 304 Stainless steel and then milled to suit the S58 wedge fitment design Port Sizing:- At Walton Motorsport we utilise stubs in the construction of our manifolds and as a result the flange ports are sized taking this into account in 3mm thick material. We can produce these in traditional port sizing when not using stubs, or for thinner gauge material. Inconel 625 is also available at request. Please call 01494 715206 or email sales@waltonmotorsport.com with any specific requirements or questions regarding this product *These flanges are designed to fit onto the head with little movement. Our hole sizes and positions are designed to account for the acceptable shrinkage tolerances; we cannot be held responsible for excess shrinkage with DIY manifold construction.*
