Our 3” exhaust system for the Hilux replaces the entire factory exhaust system, from either the DPF, or the turbo back. The mandrel bent design, with our straight-through hotdog resonator eliminates the restrictive factory muffler & exhaust piping, offering much freer flow, and a deep throaty exhaust note with no annoying drone inside the cab. The mandrel bends and straight through muffler or resonator on our Hilux exhaust system ensure the highest possible flow, and along with that comes maximum performance and fuel economy. NOTE: Talk to us about more options for your Hilux. We have many configurations to suit what you'd like!
