SPD Performance SS Catted Downpipes, with built-in Turbo Adapters – 3.5L Ecoboost (2017- 2020 F150 Raptor)

Needing ultimate performance, MPG’s and sound from your 2017 – 2020 3.5L Ecoboost F150 Raptor? Look no further! Our newly re-designed direct bolt-on catted downpipes use the highest grade EPA approved catalytic converters or GESI G-Sport UHO catalytic converters and larger 3″ diameter mandrel bent tubing which improves throttle response, mileage and overall performance while reducing turbo lag and exhaust temperatures. We built in the turbo adapters by using CNC laser cut 1/2″ 304ss flanges and TIG & MIG welded 3″ 304ss mandrel bend tubing for ultimate flow. We installed 4″ flex pipes  to absorb shock from engine movement and chassis flex.  Our downpipes do not require custom tuning and can be used as a factory downpipe replacement. Our catalytic convertors are made in the USA and are designed to be used in racing applications.  All hardware, turbo gaskets and stud bolts are included with these downpipes.

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, gaskets and stud extractor are included

We use EPA approved federal catalytic converters but you are responsible to verify that they are legal with your state and county laws.
