Frequently Asked Questions

Will this outback exhaust fit my Holden Rodeo?

Yes, Outback Exhausts are specifically designed for Holden Rodeo TF series models with the 2.8L 4JB1 turbo diesel engine manufactured between October 1998 and February 2003. It will NOT fit earlier TF models (1988-1998 with 4ZD1 or 4ZE1 engines) or later RA models (2003+).

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

While results vary based on vehicle condition and other modifications, most customers report noticeable improvements in throttle response and mid-range torque. The reduced backpressure typically results in 8-15% gains in usable power and torque, with the most significant improvements felt during acceleration, towing, and hill climbing. Turbo spool is noticeably quicker, reducing lag and improving drivability.

Is this Outback exhaust louder than the factory system?

This system produces a deeper, more purposeful diesel tone compared to the factory exhaust, but it's not excessively loud. The sound level is ideal for those who want improved performance without drone or excessive cabin noise during highway cruising. It's noticeably quieter than straight-through systems while still delivering excellent flow and a satisfying exhaust note under acceleration.

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

This is a bolt-on system designed for straightforward installation. Experienced home mechanics with basic tools, a jack, and axle stands can typically complete the installation in 2-3 hours. The turbo back design means you'll be working from the turbo outlet rearward. However, professional installation is recommended if you're not comfortable working under your vehicle or dealing with seized exhaust bolts. All necessary gaskets (excluding turbo gasket) 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.

Will this exhaust improve fuel economy?

Many customers report improved fuel economy, particularly during highway driving and when towing. The reduced backpressure and improved turbo efficiency allow the engine to operate more efficiently. Typical improvements range from 5-10%, though results depend on driving style, vehicle condition, load, and terrain. The biggest gains are usually seen during steady-state highway cruising.

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. It's significantly more resistant to rust than mild steel systems and will maintain its appearance and structural integrity for 15-20+ years in typical use. The stainless construction is especially important for beach driving, river crossings, and coastal environments where salt exposure accelerates corrosion.

Why 2.5" diameter instead of 3"?

The 2.5" diameter is optimized for the 4JB1's power output and turbo characteristics. It provides the ideal balance between flow and exhaust velocity, ensuring strong low and mid-range torque while still supporting top-end power. A 3" system can actually reduce performance on a stock or mildly modified 4JB1 by slowing exhaust velocity too much, resulting in turbo lag and reduced low-end torque. The 2.5" diameter is the sweet spot for street-driven TF Rodeos.

How long does shipping take?

Yes, Outback Exhausts ships worldwide. 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 item (approximately 20kg), so freight times may vary by location. Full tracking information is provided for all shipments so you can monitor your delivery.
