Frequently Asked Questions

Will the outback exhaust improve performance?

Yes, the 3.5" mandrel bent design reduces exhaust back pressure, resulting in improved throttle response, better fuel efficiency, and modest power gains. Most customers report noticeably improved drivability, especially when towing or loaded.

How does the outback exhaust sound?

The outback exhaust produces a deep, refined tone that's noticeably sportier than stock without being overly loud. It enhances the diesel character while remaining comfortable for daily driving and highway cruising.

What's included in the 5-year warranty?

The Outback Exhausts 5-year warranty covers manufacturing defects, material failure, and weld integrity under normal use. It does not cover damage from accidents, improper installation, or modifications.

Do I need to tune my vehicle after installing the outback exhaust?

No tune is required. The outback exhaust works perfectly with the factory ECU calibration. However, many customers choose to add a tune later to maximize the performance benefits of improved exhaust flow.

How long does shipping take?

Most orders ship within 1-2 business days. Delivery times vary by location: metro areas typically receive orders within 5-7 business days, while regional areas may take 10-12 business days. Express shipping options are available at checkout.

Can I install the outback exhaust myself?

Yes, the Outback exhaust is a bolt-on system designed for DIY installation. You'll need basic hand tools, jack stands or a hoist, and 2-3 hours. However, professional installation is recommended if you're not confident working under your vehicle.

What's the difference between DPF-back and turbo-back?

A DPF-back system (like this one) replaces the exhaust from the DPF outlet to the rear, retaining the factory DPF. A turbo-back system replaces everything from the turbo outlet, including the DPF.
