EXTRACTORS & 2.5″ EXHAUST – Toyota Landcruiser HZJ79 Series 4.2L 1HZ

Overview

Unlock reliable gains from your 70 Series with this complete Extractors & 2.5″ Exhaust package engineered specifically for the Toyota LandCruiser HZJ79 4.2L 1HZ. Replacing the factory cast manifold and restrictive pipework with tuned-length extractors and a mandrel-bent 2.5″ system improves flow, reduces back pressure and helps lower EGTs under load. Consequently, you’ll feel stronger low-down torque, smoother throttle response and a deeper, refined note on the highway. Built for touring and towing, this kit is a dependable, bolt-on upgrade for work and adventure.

Key Features

• Vehicle-specific extractors matched to the Toyota 1HZ port geometry for efficient scavenging and improved cylinder balance.
• Mandrel-bent 2.5″ (63.5 mm) pipework maintains constant diameter through bends for consistent flow.
• Heavy-duty muffler delivers a clean, non-drone exhaust note ideal for highway cruising and towing.
• Direct bolt-on fitment using factory mounting points to streamline installation and minimize downtime.
• Reduced exhaust gas temperatures under sustained load to support engine longevity on long climbs.
• Available extractor finishes to suit your build and thermal needs (see options below).
