Performance Improvements You'll Experience

This turbo back system dramatically reduces backpressure by up to 40% compared to the restrictive factory exhaust, allowing your 4JB1 turbo diesel to breathe freely. Expect improved throttle response with noticeably reduced turbo lag, stronger mid-range torque for towing caravans, trailers, and boats, increased top-end power for highway overtaking and loaded driving, lower exhaust gas temperatures for improved engine longevity, quicker turbo spool for more responsive acceleration, and potential fuel economy gains of 8-12% under highway driving conditions.

Frequently Asked Questions

How much power gain can I expect from an Outback Exhaust?

The 2.5" turbo back system typically delivers 10-18 horsepower gains at the wheels, with even more substantial improvements in torque throughout the rev range. Most owners report the biggest difference in throttle response, reduced turbo lag, and stronger mid-range pulling power.

Is the Outback Exhaust louder than the factory system?

Yes, this system produces a deeper, more aggressive diesel tone compared to the factory exhaust. It has a satisfying rumble at idle and a purposeful growl under acceleration, but it's not excessively loud during highway cruising. The sound level is ideal for those who want improved performance and a more engaging exhaust note without excessive cabin noise.

Can I install the Outback Exhaust myself or do I need a mechanic?

This is a bolt-on turbo back system designed for straightforward installation. Experienced home mechanics with proper tools, a quality jack and stands, and basic exhaust work experience can complete the installation in 2-4 hours. The turbo back design means you're working from the turbo outlet rearward. However, professional installation is recommended if you're not comfortable working under your vehicle or dealing with potentially seized exhaust bolts, which are common on older TF Rodeos. All necessary gaskets and hardware are included.

What's included in the 5-year warranty?

Our 5-year warranty covers manufacturing defects, material failures, weld integrity, and corrosion perforation of the stainless steel components under normal use conditions. The warranty does not cover damage from accidents, improper installation, modifications, or abuse.

What material is the exhaust made from and how long will it last?

This system is constructed from premium 409-grade stainless steel, which offers excellent corrosion resistance and durability in Australian conditions. The stainless steel resists rust far better than mild steel systems, which is especially important for beach driving, river crossings, coastal environments, and the high-temperature operation of turbocharged diesels.

What's the difference between this and the later RA Rodeo exhaust?

This exhaust is specifically designed for the TF Rodeo (1991-1998) with the 2.8L 4JB1 engine, which is a different engine and chassis from the later RA Rodeo (1998-2003) with the 3.0L 4JH1-TC engine. The mounting points, pipe routing, and dimensions are completely different. Make sure you order the correct exhaust for your specific Rodeo model and engine code to ensure proper fitment.

How long does shipping take?

Yes, we ship world-wide with fast dispatch. Most orders are dispatched within 24 hours. Full tracking information is provided for all shipments so you can monitor your delivery progress.
