Upgrade the downpipes on your 2025 twin-turbo SUV
Give your 2025 Explorer ST or Aviator a Kooks catted front exhaust upgrade while retaining the compatible mid-pipe connection. These stainless downpipes use 400-cell GREEN cats and join the OEM or compatible aftermarket mid-pipes.
SKU: 15123300
The 2025-specific downpipe choice
15123300 is the 2025 application. The earlier 2020-2024 range has a separate SKU, so choose the front pipework for the model year of your own SUV.
Know the catalyst application limit
These GREEN cats are rated for applications up to 750 RWHP, or rear-wheel horsepower. Choose them within that catalyst capacity for your engine build. Kooks recommends adding the separate 9003A O2 spacer equipment.
Matching products
Add the recommended 9003A O2 spacer equipment to your downpipe order; it is supplied separately.
