Mazda Miata MX-5 NA 1.6L B6ZE Stainless Steel 4-2-1 Exhaust Header
XS-POWER Performance Header for the 1.6L NA Miata
Upgrade the exhaust system on your first-generation Mazda MX-5 Miata with the XS-POWER stainless steel 4-2-1 performance header, designed for early NA chassis models equipped with the 1.6L B6ZE engine and manual transmission.
The lightweight NA Miata is one of the most recognized driver's cars of its generation, and improving exhaust flow is a popular upgrade for owners looking to enhance the character and performance of the naturally aspirated 1.6L engine.
This performance header replaces the factory exhaust manifold with a tubular 4-2-1 runner configuration and terminates in a 2-inch outlet. Stainless steel construction provides a performance-oriented upgrade while maintaining the clean appearance expected from an XS-POWER exhaust component.
Header and flange gaskets are included along with the supplied installation hardware, giving you the major components required for installation.

4-2-1 PERFORMANCE HEADER DESIGN
The XS-POWER header uses a 4-2-1 configuration: four primary runners merge into two secondary runners before combining into a single exhaust outlet.
This layout is well suited to a naturally aspirated street-performance application where usable engine response and efficient exhaust flow across a broad operating range are important.
Combined with the 2-inch outlet, the tubular header provides a performance-oriented exhaust path for the lightweight 1.6L NA Miata platform.
DESIGNED FOR THE 1.6L NA6 MIATA
Early first-generation Mazda Miata and MX-5 models equipped with the 1.6L engine are commonly identified by enthusiasts as NA6 Miata applications.
This header is specifically intended for the early 1.6L configuration rather than the later 1.8L Miata application. That distinction is important when selecting an exhaust header because engine and exhaust configurations differ between applications.
If you are building or restoring an early NA Miata and want a stainless steel performance exhaust manifold, this XS-POWER 4-2-1 header provides an application-specific option for the 1.6L platform.

INSTALLATION INFORMATION
Professional installation is recommended. Before final installation, verify gasket alignment, exhaust-system condition, oxygen-sensor placement where applicable, chassis clearance and transmission clearance.
Exhaust components experience repeated thermal expansion and contraction. Header fasteners should be properly torqued during installation and rechecked after the appropriate initial heat cycles.
