Everything You Need to Know About F150 Ecoboost Downpipes

The F-150 Ecoboost downpipe is a crucial component for any serious off-roader or enthusiast. It's a high-performance exhaust system designed to maximize power and efficiency.

A stock downpipe can limit the potential of your F-150 Ecoboost, but upgrading to a high-performance downpipe can make a significant difference. In fact, a well-designed downpipe can increase horsepower by up to 20 horsepower and torque by up to 30 lb-ft.

The F-150 Ecoboost engine produces 325 horsepower and 400 lb-ft of torque, but it can produce even more with the right downpipe. A high-performance downpipe can also improve fuel efficiency and reduce emissions.

The cost of a high-performance downpipe can vary depending on the brand and quality, but it's generally a worthwhile investment for serious off-roaders and enthusiasts.

If you're looking to upgrade your F-150's downpipe, you've got some great options to consider. The cp-e™ F-150 Catted Downpipe offers a 5% gain in performance throughout the RPM band, thanks to its CNC-milled Stainless Steel turbo flange and full 3″ to 3.5″ mandrel bent 304 stainless steel design.

One of the standout features of the cp-e™ downpipe is its extra O2 bung for adding a wideband sensor, making it a great choice for those who want to fine-tune their engine's performance. The downpipe also features a laser cut stainless steel bracket, which is welded onto the stock downpipe support mount for a secure fit.

Another option to consider is the AMS Performance 2015-2020 Ford F-150 Ecoboost 3" Downpipe Kit. This kit features a 24.7% increase in cross sectional area at the inlet, making it one of the most efficient downpipes on the market. The AMS downpipes also have chamfered mounting flanges, which evenly distribute clamping force for a secure fit.

Here's a comparison of the two downpipes:

Ultimately, the choice between these two downpipes will depend on your specific needs and preferences. Both options offer high-quality performance and design, but it's worth considering the features that are most important to you.

A larger downpipe can make a big difference in your F-150 EcoBoost's performance.

The less resistance inside the piping itself allows the turbo to spool quicker, producing more boost and having a smoother powerband. This can be especially beneficial if you need power at all ranges of the rpm.

Upgrading your downpipe can be a game-changer, but it's not the only thing you'll want to consider. A tuner for the computer is not a must, but it can help immensely when combined with the downpipe.

Dyno graphs have shown a significant gain in power and torque when using an aftermarket tune with a downpipe. Without the tune, the numbers are still impressive, but not as high as they could be.

For most F-150 applications, a 3” downpipe is the go-to size due to its large benefits and possible fitment, despite the tight space.

AMS Performance's 3" Downpipe Kit for the 2015-2020 Ford F-150 Ecoboost is a great example of a well-designed downpipe, featuring stainless steel construction and a 24.7% increase in cross-sectional area at the inlet.

This increased area allows exhaust gases to flow more efficiently, letting your turbos spool quicker and delivering a ton of power, faster.

The size of the downpipe is a crucial consideration. For most F-150 applications, 3” is the go-to size.

This size offers large benefits, including improved performance and reduced backpressure. The fitment, while tight, is possible.

In fact, the biggest issue with upgrading truck downpipes is often size, particularly in applications with turbocharging.

For the 2015-2020 Ford F-150, a 3" downpipe is a popular choice, but it's essential to consider the size of the downpipe when upgrading. The biggest issue with upgrading truck downpipes is size, and for most F-150 applications, 3" is the go-to size.

The benefits of a 3" downpipe are significant, with 5% gains throughout the RPM band. However, fitment can be tight, but it's possible with the right design. For example, the cp-e™ F-150 EcoBoost Downpipe features a laser-cut stainless steel bracket that welds onto the stock downpipe support mount, accommodating the stock mounting.

A 3" downpipe can be restrictive, but some manufacturers have designed their downpipes to use the stock downpipe support mount. The AMS Performance Ford F150 3.5L EcoBoost Downpipe features a 24.7% increase in cross-sectional area at the inlet, making it one of the largest on the market.

When choosing a downpipe, consider the materials and construction. The cp-e™ F-150 EcoBoost Downpipe features a satin finish that not only gives a uniform clean finish but also strengthens the stainless steel and welds for added reliability. Additionally, the downpipe is made in the U.S.A. and backed by a lifetime warranty.

Here's a comparison of some key features of the cp-e™ and AMS Performance downpipes:

Ultimately, the right downpipe for your Ford F-150 will depend on your specific needs and preferences. Consider the size, materials, and construction of the downpipe, as well as any additional features that may be important to you.
