Frequently Asked Questions

Do I need an extractor for the outback exhaust system to fit?

Yes, the Outback exhaust system includes a mild steel extractor.

Will the outback exhaust fit my Toyota Landcruiser 105 Series?

The outback exhaust system is specifically designed for the HZJ105 wagon model with the 4.2L 1HZ naturally aspirated diesel engine manufactured between 1998 and 2007.

What performance gains can I expect from the Outback exhaust system?

When combined with a quality extractor, you'll experience improved throttle response, reduced exhaust gas temperatures (EGTs), slightly better fuel efficiency, and a deeper, more refined exhaust note. The 2.5" diameter provides optimal flow for the naturally aspirated 1HZ engine without being oversized.

Why is 2.5" the right size for the 1HZ engine?

The 2.5" diameter is specifically sized for the 1HZ naturally aspirated diesel engine's exhaust flow characteristics. Unlike turbocharged engines that benefit from larger diameter systems, the 1HZ performs optimally with 2.5" tubing, maintaining proper exhaust velocity while reducing back pressure.

How difficult is the installation of the Outback exhausts? Can I fit it myself?

This outback exhaust is a bolt-on replacement system designed for straightforward installation. Most mechanically-inclined owners can install it with basic hand tools, a jack, and jack stands. Professional installation is recommended if you're not comfortable working under your vehicle. Installation typically takes 3-5 hours.

What's included in the 5-year warranty?

The Outback Exhaust's 5-year warranty covers manufacturing defects and material failures under normal use. This includes weld integrity, material corrosion, and component failure. The warranty does not cover damage from accidents, improper installation, modifications, or use without a properly fitted extractor. Extractors comes with 2 year warranty.

How does the outback exhaust improve the 1HZ engine's performance?

The 1HZ is a naturally aspirated engine that benefits from reduced exhaust restriction. Our mandrel-bent 2.5" system maintains consistent diameter throughout, eliminating the crimped bends found in factory systems. Combined with an extractor, this reduces back pressure, lowers EGTs, and allows the engine to breathe more efficiently, particularly under load when towing or climbing.
