The 300 Series continues the Landcruiser legacy - tough, capable and built to perform. Like the VDJ70 and 200 Series before it, it’s made to handle anything you throw at it, but there’s still serious performance waiting to be unlocked. This single exit 4” exhaust system is handmade in house from brushed 304 stainless steel and TIG welded for strength and precision. Designed for maximum durability and flow, it delivers the performance and tone your 300 Series deserves. TURBO BACK The turbo back system is the ultimate choice for maximum performance and improved exhaust flow. It delivers the largest gains in power and efficiency of any exhaust set up. The turbo back system bypasses the factory DPF entirely. This modification may be illegal in most areas and could void your vehicle warranty, so it is intended for off road and track use only. A remap is required to ensure the engine runs safely and performs optimally with this set up. DPF BACK The DPF back system works with your standard DPF while still delivering the signature GSL exhaust sound. If you want a great sounding exhaust for daily driving rather then maximum power, this is the ideal choice. It keeps your vehicle compliant, runs a little quieter for daily use and looks just as sharp from the rear so you don't compromise on style or practicality. Whether it’s your daily driver or your weekend adventure rig, this 300 Series exhaust delivers more power, better flow and the confidence to tackle any off road challenge.
