3' Stainless Steel DPF-Back Exhaust – Holden Colorado RG 2.8L Turbo Diesel (2016+)
Upgrade your factory exhaust system with this high-flow PPD Performance 3' polished stainless steel DPF-back unit.
This system is designed specifically for the Holden Colorado RG 2.8L Turbo Diesel (2016+), offering increased exhaust flow, deeper tone, and improved durability over the factory system. It’s a great alternative to rust-prone mild-steel options — perfect for coastal or off-road use.
Built from 304-grade stainless steel, this Holden Colorado Exhaust upgrade is corrosion-resistant, easy to install, and one of the best-value Holden 4x4 Exhausts on the market — similar systems often cost three times as much.
DPF-Back Specifications:
- 3' 304-grade stainless steel piping – 1.5mm wall thickness
- Mandrel bent and TIG welded for optimal flow
- 2-bolt and slip-joint flanges for bolt-on fitment
- Heavy-duty hangers with dual mounting points
- Includes premium Fire Ring gaskets and bolts
This system offers excellent performance gains and a bold exhaust note on all 2016+ RG models running a DPF.
Add a tune for even more power: While tuning isn’t required for this exhaust, pairing it with the PPD Performance Remapper unlocks serious torque and responsiveness. The Remapper allows us to increase fueling and boost safely to take full advantage of your upgraded Holden Stainless Exhaust. It’s the ultimate power combo for turbo diesels. |

Pre-Order Information
Items where the “Add to Cart” button is replaced with “Pre-Order” are classified as pre-order items. When placing a pre-order, a warning box will appear outlining the terms and conditions, including the estimated delivery timeframe.
Please keep the following in mind:
Stock is not on hand – we have no control over delivery times until the stock arrives.
Patience is required – pre-ordering secures your item, but fulfilment depends on supplier availability.
High-demand items – pre-orders are the best way to lock in popular products, which often sell out before they even land.
Allow a buffer – please add 2–3 weeks to the provided ETA to account for any unforeseen delays beyond our control.
Pre-ordering ensures you don’t miss out on in-demand products, and we’ll keep you updated as soon as your order is ready to ship.
