Advance Headers High-Performance Mild Steel Exhaust Extractors for JEEP 4.0L EFI Inline 6
The Advance Headers Performance Exhaust Extractors (A144) are precision-engineered for the legendary 4.0-Litre Inline 6-Cylinder EFI petrol engine found across the Jeep Cherokee, Grand Cherokee, and Wrangler platforms (1994–Onwards). This heavy-duty tubular manifold upgrade replaces your notoriously crack-prone factory cast or multi-piece log manifold with a durable, high-flowing design optimized to maximize exhaust scavenging velocity and boost low-to-mid range off-road torque.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Performance Exhaust Extractor Header Assembly (Standard Finish)
Key Features:
- Tuned mandrel-bent primary piping configuration delivers an unobstructed path for exhaust gases, dropping restrictive backpressure for crisper throttle response
- Substantially optimizes low-end torque delivery and mid-range pulling power—perfect for off-road technical rock crawling, beach driving, and remote outback touring
- Heavy-duty mild steel construction structurally built to withstand intense engine bay temperatures and punishing 4x4 operating conditions
- Thick, precision laser-cut head flanges guarantee a completely flush mating surface to guard permanently against thermal face distortion and standard manifold leaks
- Backed by a comprehensive 1-Year Australian Manufacturer Warranty for structural peace of mind
