Extractors, headers — whatever you call them — are a more efficient "tubular" version of an Exhaust Manifold.

Overview

• Some header do not allow the stock intake manifold to fit. You can grind the intake to fit

• Some head hit the stock block breather pipe. Make a custom pipe.

• Headers for 1200 fit all body styles: ute, wagon, coupe and sedan

• Headers/extractors fit both ways (A12 fits A14 and vice versa). However because A14, A15 and early A13 are "tall" blocks the header is raised up 15mm. So A12 headers on A14 engine may hit the floor.

• Headers for A-series engines bolt to any A-series engine. Exhaust port bolt pattern is identical for all A-series engines. port shape and size is identical within 1 or 2 mm

• Headers for a particular Datsun model may not fit another. For example, Vanette or B310 headers may or may not fit B110 due to the shape of the firewall and floor

• Like any header they may need some tweaking of the flange, not because of the engine but because of poor manufacturing of the header

Suppliers

• Yourself. If you know how to weld, You can make your one out of some steel tubing and a bit of 10mm plate for the flange

Nissan Competition

Nissan Sports Options Department tubular headers are a direct replacement for the cast iron GX manifold. They are superior to a "shorty" header in that these are a dual outlet type, and are collected together in the exhaust extension.

Shorty Headers

Shorty header is designed to replace cast manifold. Easy packaging comes at the expense of a full length collector. The performance is lacking compare to a typical header.
