Our CVF Stainless Steel Downpipes will release all the hidden horsepower and torque your turbocharged EcoBoost 3.5L F-150 has to offer by facilitating more efficient airflow directly from the turbos without removing the catalytic converters.
You will not only experience increased power and performance but also realize a more aggressive note to the sound of your exhaust when compared to the stock downpipes.
Manufactured from high quality 3" T304-grade stainless steel tubing for superior strength and corrosion resistance, these CVF downpipes feature smooth mandrel bends throughout the piping to improve exhaust flow, equaling more power and better performance.

    Great Fit and Finish!

    I bought these downpipes to replace my OEM unit which had a failing catalytic converter. The price for these compared to other brands and OEM replacements is unbeatable! Installation was pretty straightforward and the parts are well made. If you are installing this, you might as well go ahead and upgrade the turbo adapters while you are at it. The truck feels more responsive and sounds great!

    I needed new cats for my 2015 f150 3.5 eco boost and decided to go aftermarket. I watched some videos on installation, but decided to have them installed by a shop.

    When I picked up the truck the mechanic commented on how nice the pipes were and said “too bad you’ll never see them.” He couldn’t be more right. Out of the box they are well crafted with perfect welds and are just beautiful to look at. I upgraded with the turbo adapters and kit. And much to my surprise it came with antifoulers. All were installed in about 2 hours.

    Cold start gives it a slightly deeper tone and you can hear the turbos kick in. Driving it also has a slightly deeper tone and the turbo spooling is spectacular… noticeable, but not obnoxious.

    Performance wise the truck is tuning smooth, shifts great, and I notice a mpg improvement. Not sure if all the performance improvements are from the pipes though because I also changed the plugs and coils. But with 165000 miles I can assure you I wish I did this upgrade 150000 miles ago. Great quality product, no CEL’s and outstanding sound and performance from a quality product. Thank you CVF!

    These were an easy install and sound fun with a little pop and soft whistle. They're not too loud or squeaky, and I noticed an increase in fuel economy! A cel came up, but send a quick email to CV Fab, and the issue will be addressed. I plan to add a cold air intake, so I'm instead to see how it sounds and improves even more!
