Give your twin-turbo SUV a catted downpipe upgrade
These Kooks GREEN downpipes replace the front catalytic pipework on your Explorer ST or Aviator, retaining the connection to compatible OEM or aftermarket mid-pipes. The stainless construction and 400-cell GREEN cats make them a dedicated front exhaust upgrade for the twin-turbo application.
SKU: 15113300
Retain your mid-pipe connection
The downpipes connect to the OEM or compatible aftermarket mid-pipes. You can upgrade the front section while planning the rest of the exhaust around the system already on your SUV.
Keep the catalyst limit clear
The GREEN cats on this SKU are rated for applications up to 750 RWHP, meaning rear-wheel horsepower. This is catalyst capacity for your engine build. Kooks recommends the separate 9003A O2 spacer equipment.
Matching products
Add the recommended 9003A O2 spacer equipment to your downpipe order; it is supplied separately.

Frequently asked questions
Do I need to replace the mid-pipes too?
The downpipes connect to the OEM or compatible aftermarket mid-pipes.
Does the 750 RWHP figure mean a gain from fitting these?
It is the upper application rating for these GREEN cats. It is not an added horsepower figure.
