AMS Performance Street Downpipes for P552 Ford F-150 Raptor

Improving horsepower potential through increased exhaust gas flow efficiency.

The first step to making more power on any twin turbocharged engine is to allow the turbos to breathe easier. Unrestricting the intake and exhaust paths into and out of the turbos can make improvements in turbocharger spool time, boost threshold, and overall power output. The AMS Performance 2017-2020 Ford Raptor 3.5L EcoBoost Street Downpipes have been designed with that principle in mind, creating a free flowing exhaust path out of the turbochargers to improve all aspects of engine performance. Utilizing EPA compliant catalytic converters from industry titan MagnaFlow, the AMS downpipes for the Raptor are the perfect solution for increased performance and OEM-like fitment and emission control.

Engineered To Win

The AMS Snailworks© Engineering Team has designed the AMS Performance 2017-2020 Ford Raptor 3.5L EcoBoost Street Downpipes to be a direct bolt-in install without hacking up your prized possession. The AMS Engineers utilized SOLIDWORKS© CAD software to blueprint the entire unit with smooth features and geometry to optimize exhaust flow. The design of the new AMS Performance 2017-2020 Ford Raptor 3.5L EcoBoost Street Downpipes positions it to be the best performing, highest quality, and easiest to install unit on the market.

AMS’ engineers have even gone the extra mile and designed the inlet flanges to bottom out on the OEM studs and have chamfered the downpipe mounting flanges to evenly distribute clamping force, resulting in a perfect seal. Extra attention was given to enlarging the factory connection to the turbo outlets and the AMS Downpipes were able to achieve a 24.7% increase in cross sectional area at the inlet, the largest on the market. These enlarged downpipe inlets match perfectly in size to their AMS Turbine Housing Adapters (sold separately).


  • Significant rise in the volume of exhaust emitted beyond the standard level.
  • There has been a 24.7% expansion in the cross-sectional area at the inlet of the downpipe.
  • The construction of the pipe involves mandrel bending and TIG welding, using 3″ diameter 304 stainless steel.
  • The use of Magnaflow EPA compliant catalytic converters ensures that there are no check engine light (CEL) issues.
  • The maximum clearance available for the crossmember ensures a fitment that closely resembles the original equipment manufacturer (OEM) specifications.
  • While compatible with OEM specifications, the design of the product is optimized for optimal performance when paired with AMS turbine housing adaptors.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only.

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at [email protected] with any inquiries.
