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.

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

DPF Back vs Turbo Back - What's the Difference?

This DPF back Outback exhaust system replaces the exhaust from the Diesel Particulate Filter (DPF) to the tailpipe, while retaining your factory DPF and all emissions equipment. This configuration:

• Still delivers substantial performance gains through improved post-DPF flow
• Provides a cost-effective upgrade path without emissions modifications

Frequently Asked Questions

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

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

What's the difference between DPF back and turbo back exhaust?

A DPF back system replaces the exhaust from the DPF to the tailpipe, retaining your factory DPF and emissions equipment. A turbo back system replaces everything from the turbo to the tailpipe, including the DPF. 

What performance gains can I expect from this 3.5" exhaust?

Most customers report noticeable improvements in throttle response, better mid-range torque for towing and overtaking, reduced exhaust gas temperatures, and improved fuel economy by installing Outback exhaust system. The larger 3.5" diameter provides maximum flow benefits, especially when towing or carrying heavy loads.

How difficult is installation? Can I fit it myself?

Outback exhaust system is a direct bolt-on replacement for your factory exhaust from the DPF back. Mechanically inclined owners with proper tools and workspace can install it themselves.

What's included in the 5-year warranty?

Outback exhausts' comprehensive 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 - particularly under acceleration and load after installing Outback exhaust system. The sound is refined and suits the character of the 79 Series without being excessively loud or causing drone.

Can I run this exhaust with a performance tune?

Yes, this exhaust is an excellent complement to performance tuning. The increased flow capacity of the 3.5" system allows tuned engines to breathe more efficiently, maximizing the benefits of both modifications. Many customers install the exhaust first, then add tuning later.

Do you offer Australia-wide shipping?

Yes, Outback exhausts offer nationwide delivery across Australia with careful packaging to ensure your exhaust arrives in perfect condition. International shipping is also available.
