More About Custom Exhaust Manifold & Header Fabrication Service from a 3D Printing & CNC Source Factory
We are an international B2B manufacturer specializing in integrated metal 3D printing and CNC precision machining. With deep expertise in custom automotive exhaust systems, we provide high-quality performance exhaust manifold solutions for clients worldwide.
Our core services focus on performance modification and racing aftermarket. We also offer customization for automotive tier suppliers, helping customers achieve product upgrades and performance improvements.
Using advanced metal 3D printing technology, we produce one-piece integrally formed exhaust manifolds that overcome traditional manufacturing limitations. We have specialized expertise in independent-channel exhaust manifolds for 992-style high-performance platforms.
We offer two premium material options: 310S stainless steel or Inconel 625 nickel alloy, with wall thickness strictly controlled above 2.75mm to balance strength and durability.
310S stainless steel provides excellent high-temperature resistance and oxidation resistance, stable above 1150℃, ideal for performance upgrades and daily driven vehicles.
Inconel 625 nickel alloy delivers exceptional strength and corrosion resistance from low temperatures up to 1093℃, designed for racing and extreme high-performance use.
Both materials support personalized fitment for a wide range of high-performance vehicles.
We adhere to strict production standards and can customize:
1. 3D-printed one-piece non-equal-length independent-channel headers
2. 3D-printed one-piece equal-length independent-channel headers
Our equal-length header solutions built for 992 (911) style platforms are a representative benchmark product.
An equal-length header is engineered so each cylinder’s exhaust runner has consistent length and path, reducing exhaust interference and improving high-RPM efficiency.
Many factory manifolds prioritize durability and emissions compliance but can create exhaust interference and higher backpressure at high RPM, limiting performance potential.
Our custom equal-length headers feature a 3D-printed outlet with a 120-degree three-in-one structure and optional black thermal coating, offering a premium appearance and smoother, more efficient exhaust flow.
We are an industrial-grade metal 3D printing manufacturer with:
(1) 30 high-end SLM metal 3D printers
(2) 14 CNC precision machines
(3) 60 imprimantes 3D en plastique
(4) 6 specialized production facilities for 3D printing and CNC finishing
Welcome to contact us for details.
We have NO MOQ (Quantité minimum de commande). Rapid prototyping and custom production are available.
