Please note: 2016+ cars have a Diesel Particulate Filter (DPF). If installed on these cars, this system removes the DPF. A tune is required when removing the DPF, this can be completed with one of our remapper units (linked below). Disclaimer: DPF removal components are designed for off-road use only with specific exemptions, they are not legal for road use. Please consider this before purchasing and installing.
Replace the restrictive factory system with a full 3" Holden Stainless Exhaust upgrade from PPD Performance. Designed for the 2.8L Holden Colorado 7 and Trailblazer, this turbo-back system delivers the power, sound and flow your vehicle deserves.
This polished stainless steel exhaust system is crafted specifically for the Holden Colorado 7 Wagon and Trailblazer platform. Say goodbye to rusted mild steel and poor factory flow — and experience real performance gains on your Holden Colorado Exhaust.
Built from premium 304-grade stainless steel, this is one of the most cost-effective Holden 4x4 Exhausts available. Comparable systems can cost three times as much.
This is a proven design producing real gains in throttle response, low-end torque, and overall engine efficiency on the Holden Colorado 7 platform.
Add a tune for even more power:While not required, pairing your new exhaust with a custom ECU tune is the best bang-for-buck upgrade for any Colorado Exhaust owner. The PPD Performance Remapper is a convenient, remote tuning solution. It lets us custom-tune your Colorado to increase boost and fueling to match the extra flow of this 3" system — unlocking serious diesel performance gains. |

PPD Performance exhausts comprise of mandrel bent, stainless pipe work, delivering uncompromising flow, performance, and sound. Mandrel bending involves placing a mandrel inside the piping, before it is bent to shape. In comparison; cheaper press bending from other manufacturers squashes the tube as it is bent, reducing flow.
Tired of your mild steel exhaust systems rusting out after a year or less? Time to shop for a stainless steel system? There’s still some things you need to be aware of. Our competitors typically advertise their exhaust products as stainless steel. Most don't stipulate the differences between ferretic 409 grade stainless steel and austenitic 304 stainless steel.
Significant differences exist between the metals that make one better for performance exhaust applications than the other. Let us explain
The corrosion resistance of your 4x4 exhaust depends on the content of chromium and nickel found in the alloy. 409 grade stainless steel is used by many manufactures due to its medium strength, formability and very low cost. Typically, 409 grade stainless steel has a chromium content of between 10.50% - 11.75% and a nickel content of less 0.50%.
Why do we use 304 grade stainless steel piping for 4x4 performance exhausts? Because it is more resistant to rusting than ferretic based stainless steels such as 409. However, because of its low ferrous content, 304 can develop a golden colour when exposed to high heat over time. In fact, the ferrous metal content is so low that magnets won’t stick to it, making the identification of 409 and 304 grade stainless steel very easy.
Put simply, 304 grade stainless is the best value material used in the 4x4 exhaust game when strength, corrosion resistance and performance are at the top of your list of priorities.
Type 304 steel is engineered with chromium and nickel content and proves to be resistant to oxidation, corrosion, and durability.
Together with a polished finish - it is a great choice for your 4x4 offering excellent corrosion resistance from exhaust emissions, moisture and beach exposure.
All PPD Performance exhausts are designed to follow the same orientation and layout as the factory exhaust, making for easy bolt on installations. Our systems utilise the standard hanger locations, which means you don't have to use anything other than the factory rubbers.
