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 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 welded 3" 304ss mandrel bend tubing for ultimate flow. We 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 


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


Pre-orders,  please allow 2-3 weeks to ship.
