The British Northwest Land-Rover Header

The Advantages of The British Northwest Header over the Stock Manifold.
Stock Manifold	British Northwest
Very Prone to cracking.	Heavy guage header. None known to crack EVER.
Restrictive to air flow.	Approximately 61% greater breathability
Steel studs prone to rust-out, breakage. must be drilled out, helicoiled & welded. Difficult and costly to repair.	Stainless blots used. Simply replace if ever broken.
Painted surface only available. Prone to early rust.	Available with 1500-degree mid-range and high-heat paint, lifetime ceramic- metallic coating in black or silver, or chrome plated.
Good low end torque properties, but limited on highway.	Inherently better high-end performance. Good low-end performance. Quick-fit kit available for even better low end torque if used off-road.
Stock pipes hot in summer.	Cooler heat-shielded tropical system available, as well as heat-insulative coatings.
Comparison with the "Other" Header.
Header pipes project 3 1/2 inches below the bottom of chassis, exposing them to off road damage from ground, tree stumps, rocks etc. Crushed header limits power to 5% or less.	Header orifice is 6 inches higher than the "other" header, and is thus fully protected by vehicle chassis.
Header fould spring shackles, which must be cut for installation.	Shorter design easily clears spring shackles.
Starter and generator must be removed to install or remove header.	Superior design allows installation & removal without removing either starter or generator.
Exposed collector gathers grass, etc. subjecting vehicle to fire.	Collector is raised up, keeping it clear and removing fire risk.
Larger-diameter pipes must be custom fabricated locally.	Pipe system available off the shelf from British Northwest Land-Rover.
Many fitted to existing small-diameter exhaust pipes.	British N.W. Free-flow pipe system is bolt on, fully flanged, sleeved and gasketed.
Steel pipes subject to rust-out.	Rust resistant aluminized pipes used throughout.
Thin steel fabrication.	Heavy-gauge construction throughout.
Floating output flange known to distort & leak.	Fixed flange construction is virtually leak-proof.
Thin gasket prone to leak. Needs frequent repair. May need multiple gaskets to seal. Frequently leaks even when newly installed.	Triple-thick premium gasket supplied is entirely trouble free.
Sold painted only. Paint burns, flakes off, etc.	Specialized coatings supplied, including heat containing materials.
Painted headers run hot.	Special coatings available to contain heat in hot climates.
Archaic four-pipe design	Superior tri-Y design proven best by research.
Must be taken to local muffler shop to fabricate custom pipes or adapter to small restrictive stock pipes.	Free-flow pipe system available off-the-shelf from British North West.
