Stainless steel exhaust manifold Mazda MX-5 NC 2.0

Exhaust manifolds for Mazda MX-5 NC 2.0 designed with an emphasis on maximum performance and precise exhaust gas flow. Each branch of the manifold has the same length with a tolerance of up to 1 mm, which optimizes torque and engine power.

The manifold is made of high-quality stainless steel, welded using the TIG method, and argon purge is used during welding to keep the internal surfaces clean and free of impurities, which improves gas flow.

Main advantages

• same length of all branches for optimal performance

• improved torque curve

• very high welding quality with full penetration

• precise 3D CAD design for perfect fitment

Power measurement result

• 204.6 HP / 226.4 Nm

• achieved only by replacing the manifold and modifying the ECU

Features

• precise design using 3D CAD (SolidWorks)

• optimized exhaust gas flow

• TIG welding with argon purge on the inner side of the manifold

• manufactured using CNC fixtures and laser-cut tubes

• precisely machined flange for perfect seating on the engine head

• tested throughout the entire season in motorsport

Why these manifolds

The result is a combination of precise design, testing, and quality manufacturing. The manifold improves engine power, increases torque, and simultaneously maintains high reliability for both sports use and daily driving.
