Push your Nissan RB20/25/26 DOHC engine build to the next level with the Artec Performance 70mm "Big Daddy" V-Band Exhaust Manifold. Engineered for high-horsepower applications, this manifold combines advanced design with investment casting technology to deliver superior strength, flow, and reliability compared to traditional fabricated manifolds.

Key Features:

• 70mm V-Band outlet for large-frame turbochargers.
• V-Band connections for secure, leak-free sealing and quick turbo changes.
• Designed for high-performance RB25 and RB26 engines.
• Built to handle extreme boost and track conditions.
• Industry leading SUS347 stainless steel investment cast exhaust manifold with allows ARTEC manifolds to deliver superior flow and efficiency. Smoother merging angles can be achieved versus traditional manifolds, and tight radius bends and runners can also be eliminated which can cause restriction.
• Rated for 1200+ wheel horsepower
• The ARTEC V-Band Ring System allows you to install turbos from all of the big brands without having to chop and change flanges or manifolds!
• Retain factory A/C and Power steering, also leaving plenty of space for running oil and water lines

Why Investment Casting?

• Unmatched Strength & Durability: One-piece cast construction eliminates welds, removing common failure points under extreme heat and boost.
• Optimised Flow: Smooth internal surfaces reduce turbulence, improving exhaust gas velocity for faster turbo spool and maximum efficiency.
• Consistent Quality: Precision moulding ensures uniform wall thickness and perfect fitment every time.
• Compact Design: Casting allows for complex shapes that maximise clearance and simplify installation in tight engine bays.
