Needing ultimate performance, MPG's and sound from your 2017 - 2020 3.5L Ecoboost F150 Raptor? Look no further! SPD newly re-designed direct bolt-on catted downpipes use the highest grade catalytic converters and larger 3" diameter mandrel bent tubing which improves throttle response, mileage and overall performance while reducing turbo lag and exhaust temperatures. SPD built in the turbo adapters by using CNC laser cut 1/2" 304ss flanges and TIG welded 3" 304ss mandrel bend tubing for ultimate flow. SPD installed 4" flex pipes to absorb shock from engine movement and chassis flex.
On all SPD Performance 304 stainless catted downpipes, you get:
- Increase in performance
- Improved turbo spool time
- Better fuel mileage
- Direct turbo bolt-on design
- NO CEL - High flow catalytic converters that do not cause check engine lights
- 304 Stainless Steel 3" mandrel bent tubing
- High grade v-band clamp for a solid seal and no leaks
- All hardware, gasket and stud extractor included
SPD uses EPA approved catalytic converters but you are responsible to verify that they legal with your state and county laws.

Performance Benefits
Upgraded downpipes allow the turbocharger(s) to spool up faster and maintain more boost than stock downpipes, resulting in increased power output and better overall engine performance. This upgrade also improves throttle response, and provides a more responsive and powerful driving experience.
Enhanced Exhaust Flow and Reduced EGTs:
High flow cats are designed to allow exhaust gases to pass from the engine and turbos more freely compared to stock catalytic converters, resulting in a reduction of backpressure and a reduction in exhaust gas temperatures (EGTs).
The use of mandrel bent tubing ensures smooth exhaust flow post-cat, which maintains reduced back pressure and exhaust gas temperatures (EGTs) for optimal performance.
Better Flow = Faster Spool = More Boost:
Reduction of EGTs and decreased backpressure allows turbocharger(s) to operate more efficiently in terms of spool time and building boost.
Build Quality:
High-Quality 304 Stainless Steel
Downpipes constructed from 304 stainless steel offer superior durability and resistance to corrosion, ensuring long-lasting performance.
