Performance Improvements You'll Experience

This 3-inch turbo back system dramatically reduces backpressure by up to 45% compared to the restrictive factory exhaust, allowing your 4JH1-TC turbo diesel to breathe freely. Expect improved throttle response with noticeably reduced turbo lag, stronger mid-range torque for towing heavy loads, trailers, and work equipment, 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 10-15% under highway driving conditions. The larger 3" diameter is specifically optimized for the 4JH1-TC's output, providing maximum flow while maintaining proper exhaust velocity for commercial and heavy-duty applications.

Perfect For

• Commercial and trade applications with heavy loads
• Towing heavy caravans, camper trailers, boats, and work equipment
• Farm work and agricultural applications

Frequently Asked Questions

Will this Outback exhaust fit my Holden Rodeo?

Yes, Outback Exhausts are specifically designed for Holden Rodeo RA series TRAY BACK / CAB CHASSIS models with the 3.0L 4JH1-TC turbo diesel direct injection engine from 2003-2007. It will NOT fit dual cab models due to different chassis and pipe routing requirements. Please verify your body type (tray back/cab chassis), engine code (4JH1-TC), and year before ordering.

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

The 3" turbo back system typically delivers 15-25 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. The turbocharged 4JH1-TC responds exceptionally well to the larger 3" diameter and reduced backpressure, making the Rodeo tray back feel significantly more responsive, especially when loaded with heavy cargo or towing.

Why 3" diameter instead of 2.5" for the tray back?

The 3" diameter is specifically optimized for tray back and cab chassis models that are typically used for heavier commercial applications, towing, and carrying significant loads. The larger diameter provides maximum flow reduction in backpressure, which is particularly beneficial when the vehicle is working hard under load. If you have a dual cab model used primarily for lighter duties, a 2.5" system may be more appropriate - contact us for the correct fitment.

Is the Outback Exhaust louder than the factory system?

Yes, this 3" system produces a noticeably deeper, more aggressive diesel tone compared to the factory exhaust. It has a strong rumble at idle and a purposeful growl under acceleration, with nice turbo whistle and wastegate sounds. The larger diameter creates a more aggressive sound profile than 2.5" systems. However, it's not excessively loud during highway cruising. The sound level is ideal for commercial operators and enthusiasts who want maximum performance and an engaging exhaust note.

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

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 3-4 hours. The tray back configuration provides better access than dual cab models. However, professional installation is recommended if you're not comfortable working under your vehicle or dealing with potentially seized exhaust bolts. All necessary gaskets and hardware are included.

Will an Outback Exhaust improve fuel economy?

Yes, many customers report improved fuel economy, particularly during highway driving and when towing or carrying loads. The reduced backpressure and improved turbo efficiency allow the 4JH1-TC engine to operate more efficiently. Typical improvements range from 10-15%, with the biggest gains seen during steady-state highway cruising and when working under load. The 3" diameter is particularly effective for fuel economy improvements in commercial applications.

How long will this exhaust last?

Our 409 stainless steel construction is built for extreme durability in commercial applications. In typical use, you can expect 15-20+ years of service life. The stainless steel resists corrosion far better than mild steel systems, which is especially important for tray backs used in agricultural, coastal, and commercial environments where exposure to salt, chemicals, and harsh conditions is common. We back this with a comprehensive 5-year warranty.

How long does shipping take?

Yes, we ship world-wide with fast dispatch. Most orders are dispatched within 24 hours. Metro areas typically receive orders within 3-5 business days, while regional and remote areas may take 5-10 business days. This is a large, heavy item (24kg), so freight times may vary by location.
