Frequently Asked Questions

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.

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 (excluding turbo gasket) 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 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.
