If you’re looking to give your Ecoboost Focus RS a serious kick in the pants, the Extreme Turbo Systems Downpipe is where it’s at. This isn’t just any downpipe; it’s the only full 3.0" downpipe made specifically for the Focus RS, and it’s crafted right here in-house. We use mandrel-bent 304 stainless steel tubing, which means you’re getting maximum airflow and a product that’s built to last.

Why settle for the factory downpipe that chokes your performance? Our design swaps out the restrictive OEM v-band connection for a 3.0" slip-fit connection that really opens things up. You’ll notice an increase in horsepower and torque, and that’s not just talk—this downpipe is made for performance enthusiasts who want to feel the difference.

One of the standout features is the GESI UHO-Series Catalytic Converter, which can handle up to 850hp while keeping emissions in check. It’s a smart move if you want to boost your ride without worrying about running afoul of emissions regulations. Plus, the entire construction is stainless steel, including the substrate, which is furnace-brazed to the mantle. That means you’re looking at exceptional durability, and the unique end-cap design keeps everything secure, so you won’t have to deal with annoying rattles.

Temperature-wise, this downpipe can handle up to 1500°F, making it perfect for forced induction setups. And for peace of mind, it comes with a 5-year/50,000-mile warranty on the shell and tube ends. Just keep in mind, this downpipe is designed to work with the Extreme Turbo Systems Catback exhaust system or other slip-fit setups, so it won’t connect to your factory exhaust.

• This downpipe will only fit ETS or other slip-fit exhaust systems. It doesn’t work with the factory exhaust.
