Performance Benefits

The 3.5" DPF-back design is engineered to handle the substantial exhaust flow from the 300 Series' powerful 3.3L V6 twin turbo diesel. By replacing the restrictive factory exhaust from the DPF onwards, this system significantly reduces back pressure. The result is improved throttle response, enhanced mid-range torque, potential fuel economy gains, and a deeper, more refined exhaust note that suits the premium nature of the Landcruiser 300.

Yes, we ship internationally to select countries. International shipping costs and delivery times vary by destination. Enter your country and postcode at checkout for accurate freight quotes. Please note that international customers are responsible for any customs duties, taxes, or import fees charged by their country. Contact us for specific international shipping enquiries.

What's included in the 5-year warranty?

Our 5-year warranty covers manufacturing defects, material failure, and weld integrity under normal use. It does not cover damage from accidents, improper installation, modifications, or extreme abuse.

What performance gains can I expect?

The 3.5" DPF-back design significantly reduces exhaust restriction compared to the factory system. Most customers experience noticeably improved throttle response, better mid-range torque delivery, and potential fuel economy improvements of 5-10% depending on driving conditions. You'll also enjoy a deeper, more refined exhaust note without excessive drone.

Does this system include a resonator?

Yes, this system features a resonator to deliver a deep, refined exhaust note that enhances the driving experience without creating excessive cabin drone on long highway journeys. It's the perfect balance of performance sound and comfort.

Is professional installation required?

This is a complete bolt-on replacement exhaust system designed for straightforward installation. Most customers with basic mechanical skills and tools can install this system in 2-3 hours. Professional installation is recommended for best results. No cutting or welding required - simply remove the factory exhaust from the back of the DPF and bolt this system in place.

How long does delivery take within Australia?

We offer nationwide delivery across Australia. Metro areas typically receive orders within 3-7 business days, while remote locations may take longer. You'll receive tracking information once your order is dispatched.

Will this fit the GR Sport or Sahara models?

Yes, this exhaust system fits all Toyota Landcruiser 300 Series wagon variants including GX, GXL, VX, Sahara, and GR Sport models, as long as they have the FJA300R 3.3L V6 twin turbo diesel engine (July 2021 onwards).

Will this exhaust rust?

Our 409 stainless steel construction provides excellent corrosion resistance for Australian conditions. While 409 stainless may develop some surface discoloration over time (especially in coastal or high-humidity areas), it will not rust through like mild steel exhausts. This is why we can confidently offer a 5-year warranty.
