Why Upgrade Your 79 Series Exhaust?

The factory exhaust system on your Landcruiser 79 Series is designed for quiet operation and cost efficiency, not performance. By upgrading to our 3" turbo back system, you'll experience:

• Enhanced throttle response for better drivability on and off-road
• Improved towing capacity with increased torque delivery
• Reduced exhaust gas temperatures for better engine longevity
• A deeper, more aggressive exhaust note without being intrusive
• Long-term durability with premium stainless steel that resists corrosion

3 Inch vs 3.5 Inch vs 4 Inch — Which Size is Right?

3 Inch: Balanced performance and efficiency. Ideal for daily driving, highway touring, and light towing. Deep, refined exhaust note.

3.5 Inch: Greater airflow and reduced back pressure. Better for moderate towing and performance builds. Deeper, more aggressive note with headroom for future modifications.

4 Inch: Maximum airflow. Best suited to heavily tuned engines and extreme towing setups. Loudest option. Can feel excessive for everyday use.

Frequently Asked Questions

Will this exhaust fit both single cab and double cab 79 Series?

Yes, Outback exhaust system is designed to fit both Toyota Landcruiser 79 Series single cab and double cab variants equipped with the VDJ79 4.5L V8 diesel engine from October 2016 onwards.

Why Choose 3.5" Over 3" Exhaust?

The larger 3.5" diameter provides even greater exhaust flow compared to a 3" system, resulting in:

• Maximum reduction in exhaust back pressure for optimal performance
• Enhanced power delivery, especially beneficial for heavily loaded or towing applications
• Improved exhaust gas temperatures (EGT) for better engine longevity
• Deeper, more aggressive exhaust note while remaining refined
• Ideal for vehicles with performance tunes or those planning future modifications

What performance gains can I expect from this exhaust?

While results vary depending on your vehicle's condition and other modifications, most customers report noticeable improvements in throttle response, better towing performance, and improved fuel economy. The reduced back pressure from Outback exhaust allows your engine to breathe more efficiently.

How difficult is the installation? Can I fit it myself?

Outback exhaust is a direct bolt-on replacement for your factory exhaust system. If you're mechanically inclined with the right tools and a suitable workspace, DIY installation is possible. However, we recommend professional installation to ensure proper fitment and optimal performance.

What's included in the 5-year warranty?

Outback exhaust's 5-year warranty covers manufacturing defects and material failures under normal operating conditions. This demonstrates our confidence in the quality and durability of our Australian-made exhaust systems.

Will this exhaust make my Landcruiser louder?

You'll notice a deeper, more purposeful exhaust note compared to the factory system, but it's not excessively loud or droning. The sound is refined and suits the character of the 79 Series without being intrusive during highway cruising.

Is the exhaust made from stainless steel throughout?

Yes, Outback exhaust system is constructed from premium-grade 409 stainless steel, providing superior corrosion resistance and longevity compared to aluminized or mild steel alternatives - essential for Australian conditions.
