Isuzu D-Max & Mazda BT-50 3″ 304 Stainless DPF Back Exhaust (07/2020-On)
If you’re looking to improve the performance, sound, and durability of your Isuzu D-Max or Mazda BT-50, our 3-inch 304 Stainless DPF Back Exhaust is the perfect upgrade. Specifically designed to suit July 2020 onwards models, this premium exhaust system delivers improved exhaust flow while retaining the factory Diesel Particulate Filter (DPF), ensuring your vehicle remains emissions compliant.
At Performance Range Services, we manufacture high-quality exhaust systems using premium 304-grade stainless steel, providing exceptional resistance to corrosion, rust, and the harsh Australian environment. Whether your vehicle is used for towing, off-road adventures, touring Australia, or everyday driving, this exhaust system is built to deliver long-lasting performance and reliability.
Designed with precision mandrel bends and quality welds, this DPF back exhaust offers an excellent fit, making installation straightforward while providing noticeable improvements in engine response and exhaust tone.
Why Upgrade to a 3-Inch 304 Stainless DPF Back Exhaust?
The factory exhaust system is designed to meet noise and emissions requirements but can restrict exhaust flow after the DPF. Upgrading to a 3-inch 304 stainless DPF back exhaust reduces back pressure, allowing exhaust gases to flow more efficiently from the turbocharger.
The result is improved throttle response, smoother acceleration, and a deeper, more refined exhaust note without excessive cabin drone. Because the factory DPF remains in place, you retain the vehicle’s original emissions equipment while enjoying the benefits of a less restrictive exhaust system.
For owners who regularly tow caravans, trailers, or boats, the improved exhaust flow can help the engine perform more efficiently under load, making long-distance touring more enjoyable.
Premium 304 Stainless Steel Construction
Unlike aluminised steel systems, 304 stainless steel offers superior corrosion resistance and is built to last in Australia’s demanding conditions. Whether you’re driving through mud, sand, rain, or coastal environments, our exhaust systems are engineered to withstand the elements.
Each system features:
- Premium 304 stainless steel construction
- Mandrel-bent 3-inch tubing
- Precision TIG and MIG welded joints
- Heavy-duty flanges and hangers
- Excellent fit using factory mounting points
- Long-lasting corrosion resistance
- Professional finish
This premium construction ensures your investment continues to perform for years to come.
