Need more performance, MPG, and sound from your 2015-2017 Ford Expedition/Navigator? Look no further! SPD’s catted downpipes use the highest grade EPA-approved catalytic converters and larger 3″ diameter mandrel-bent tubing, improving throttle response, mileage, and overall performance while reducing turbo lag and exhaust temperatures. Our downpipes do not require custom tuning and can be used as a factory downpipe replacement. Our catalytic converters are made in the USA and are designed to be used in racing applications.
On all SPD Performance’s Aluminized Steel Catted Downpipes, you get:
- Increase in performance
- Improved turbo spool time
- Better fuel mileage
- High flow catalytic converters that do not cause check engine lights
- High temp silica ceramic coated for a long life span
- Factory-style flanged clamps on all flared turbo and exit connections
- High-grade clamps for a solid seal and no leaks
- All hardware included
We use EPA-approved federal catalytic converters, but you are responsible for verifying that they are legal under your state and county laws.

Still a work in progress 2 hurricanes & 1 tornado in 2 months & your team delivered the products ahead of schedule. So at this point your entire team gets a 5 star review . For doing, the right thing to do. During difficult circumstances. The vehicles are both halfway through & my mechanics are impressed. These men are my teammates & veterans. Never met them before. That’s the best part of being a Veteran. We have a bond instantly. So we’re all in gratitude for great products, we don’t have to engineer to make the product work! On behalf of my family. Thank you!
