Frequently Asked Questions

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

Absolutely. Outback exhaust system is engineered to fit both Toyota Landcruiser 79 Series GDJ79 single cab and double cab variants with the 2.8L turbo diesel engine.

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?

You'll notice improved throttle response, reduced turbo lag, lower exhaust gas temperatures (EGTs), and potential fuel economy improvements after installing Outback Exhausts. The mandrel bent design significantly reduces back pressure compared to the factory 2.25" system.

How difficult is the installation?

Outback exhaust system is a direct bolt-on replacement for your factory exhaust. Most customers with basic mechanical skills and tools can install it in 2-3 hours. All necessary hardware and gaskets are included. Professional installation is recommended if you're not confident working under your vehicle.

What material is the exhaust made from?

The entire Outback Exhaust system is constructed from premium grade 409 stainless steel, specifically chosen for its corrosion resistance and durability in Australia's harsh operating conditions including salt water, mud, and extreme temperatures.

Does this exhaust come with a warranty?

Yes, all Outback Exhausts systems are backed by our comprehensive 5-year warranty covering manufacturing defects and material failure under normal use.

Will this exhaust be louder than stock?

Yes, you'll experience a deeper, more aggressive exhaust note compared to the factory system after installing Outback Exhaust. It's not excessively loud but provides a satisfying diesel rumble that enhances the driving experience without being intrusive during highway cruising.

Can I fit this myself or do I need a workshop?

While Outback exhaust is a bolt-on system that can be installed at home with basic tools (spanners, jack, and jack stands), we recommend professional installation if you're not experienced with exhaust work. A workshop with a hoist will make the job much easier.

Do you ship Australia-wide?

Yes, Outback exhausts offer nationwide delivery across Australia. Freight quotes are available for larger orders or remote locations.

Due to its sleek finish, Cerachrome tailpipe is the perfect blend of toughness and aesthetics.
