Installation

This is a bolt-on replacement exhaust system designed for straightforward installation. Most customers with basic mechanical skills and tools can install this system in 2-3 hours. Professional installation is recommended for best results. No cutting or welding required - simply remove the factory exhaust from the DPF outlet back and bolt this system in place.

Performance Benefits

The 3" mandrel bent design reduces exhaust back pressure compared to the restrictive factory system. You'll experience improved throttle response, better power delivery throughout the rev range, and enhanced fuel efficiency. The BT50's 3.2L P5AT 5-cylinder turbo diesel engine particularly benefits from the improved exhaust flow, with noticeable gains when towing, loaded, or climbing. The lightweight 23kg design also contributes to improved overall vehicle dynamics while delivering that distinctive 5-cylinder exhaust note.

Frequently Asked Questions

 

Will the outback exhaust improve performance on my BT50?

Yes, the 3" mandrel bent design reduces exhaust back pressure, resulting in improved throttle response, better power delivery, and enhanced fuel efficiency. Most customers report noticeable improvements in drivability, especially when towing, loaded, or climbing hills. The 3.2L P5AT 5-cylinder engine responds particularly well to improved exhaust flow.

How does the outback exhaust sound?

The outback exhaust produces a deep, refined tone that enhances the distinctive 5-cylinder character. It's noticeably sportier than stock without being overly loud. You'll hear a satisfying growl under acceleration with minimal noise at cruise - perfect for daily driving and work use.

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, modifications, or extreme abuse.

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 and will provide noticeable improvements on its own. However, many customers choose to add a tune later to maximize the performance benefits of improved exhaust flow, especially for towing and heavy-duty use.

How long does shipping take?

Most orders ship within 1-2 business days. Delivery times vary by location: metro areas typically receive orders within 3-5 business days, while regional areas may take 5-7 business days.

Do you ship internationally?

Yes, Outback Exhausts ships internationally to select countries. International shipping costs and delivery times vary by destination. Enter your country and postcode at checkout for accurate freight quotes. Please note that international customers are responsible for any customs duties, taxes, or import fees charged by their country. Contact us for specific international shipping enquiries.

Can I install the outback exhausts 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 and front pipe. A turbo-back system replaces everything from the turbo outlet, including the DPF. 

Will the outback exhausts fit the newer BT50 (2021+) or the 3.0L engine?

The outback exhaust system is specifically designed for the 2016-2022 Mazda BT50 with the 3.2L P5AT 5-cylinder engine. The 2021+ BT50 underwent a major redesign and shares its platform with the Isuzu D-Max, using different engines (3.0L and 1.9L). Please contact us if you need an exhaust for the newer BT50 - we have specific systems for the latest generation.

Does the outback exhaust improve fuel economy?

Yes, many customers report improved fuel efficiency after installing this exhaust, particularly during highway driving and when maintaining steady speeds. The reduced back pressure allows the engine to work more efficiently. However, actual fuel savings will vary based on driving style, load, and conditions.

Will the outback exhaust rust?

Our 409 stainless steel construction provides excellent corrosion resistance for Australian conditions. While 409 stainless may develop some surface discoloration over time (especially in coastal or high-humidity areas), it will not rust through like mild steel exhausts. This is why we can confidently offer a 5-year warranty.

Can I use the outback exhaust for towing?

Absolutely! The outback exhaust is ideal for towing applications. The improved exhaust flow reduces back pressure, which helps the engine breathe better under load. Many customers specifically upgrade their exhaust to improve towing performance, and the BT50's 3.2L engine responds particularly well to the reduced restriction when pulling heavy loads up to the BT50's 3.5-tonne towing capacity.

Is this the same as the Ford Ranger exhaust?

While the 2016-2022 Mazda BT50 shared its platform with the Ford Ranger PXII/PXIII and used the same 3.2L P5AT engine, there are some differences in exhaust routing and mounting. This system is specifically designed for the BT50. Please contact us to confirm fitment if you're unsure.
