Description

Overview

The 3″ Rear Muffler – Toyota LandCruiser 78 Series HDJ78R 4.2L Troopy (2001–07) by King Brown is a direct-fit rear section designed to refresh the sound and flow of your 78 Series exhaust. Built from robust 409 stainless steel, it suits Troopcarrier HDJ78R models from 2001 to 2007 and integrates with a 3-inch system. The unit replaces the rear muffler section and helps maintain low back-pressure for reliable touring and towing.
