TSM Race Honda B-Series Turbo Manifolds are designed and manufactured in the USA and are made from high-quality stainless steel .
Our TSM Manifolds are TIG-Welded and back purged to ensure the highest quality product. TSM flanges are machined flat ensuring a perfect seal, are produced in-house from ½” plate 1018 steel and are CNC-machined unlike the cheap laser-cut flanges on the market. Each stage of manufacturing is passed through our quality control team to ensure the end user gets a top-notch product.
This manifold supports up to 1200hp and is one of our best-selling turbo manifolds for a reason! The quality and performance sets the bar. Choose from a 38mm or 44mm wastegate flange.
