3″ Engine Pipe & Cat – Toyota Landcruiser 78 Series HDJ78R 4.2L Troopy (2001-07)

Description

Overview

The 3″ Engine Pipe & Cat – Toyota Landcruiser 78 Series HDJ78R 4.2L Troopy (2001–07) by King Brown is a premium high-flow upgrade designed to boost your LandCruiser’s exhaust efficiency and engine response. Manufactured from 409-grade stainless steel, this system delivers long-lasting durability and performance in harsh off-road conditions.

Built to suit the legendary 4.2L Turbo Diesel Troopy, this exhaust section replaces the restrictive factory pipework and catalytic converter with a larger-diameter 3″ mandrel-bent system. The result is smoother exhaust flow, reduced turbo lag, and improved low-end torque for towing, touring, and off-road power delivery.

• 3-inch mandrel bends for maximum gas flow and minimal back pressure.
