Purpose-built for the ultra-reliable, naturally aspirated 4.2-Litre 1HZ inline 6-cylinder diesel powerplant housed within HZJ80 chassis models, this premium upgrade arrives fully integrated with a heavy-duty exhaust flex joint. By substituting the highly restrictive factory cast iron log manifold structure with high-flowing mandrel-bent primary lines, this assembly drastically optimizes exhaust scavenging paths to deliver vital low-to-mid range torque enhancements, crisper throttle response under heavy load, and an exceptionally smooth diesel exhaust depth.\u003c\/strong\u003e\u003c\/p\u003e \n\n\u003cdiv class=\"feature-block\"\u003e \n\u003cdiv class=\"feature-content pb-6\"\u003e \n\n\u003ch3 style=\"color: #e60000;
