This product is ready to order. Orders will have an estimated 2-week lead time.
CTS Turbo Ford Raptor EcoBoost 3.5L High Flow-CATS are made to maximize exhaust flow for highest power gains. Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance. In addition to unleashing the power and performance of your 3.5L Twin Turbo, our High Flow-CATS will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust "note. While up-shifting you will enjoy a confident "punch!" as you bang through all 10 gears. The sound will be even louder if you already have an aftermarket exhaust system. We highly recommend getting our turbine adapters at the same time for improved exhaust flow and power. Product Details:
  • Designed and tested on a real car in the real world
  • Cast T304 stainless steel, TIG welded back-purged construction
  • 200 Cell High Flow-CATS - not compliant with emissions
  • Great power upgrade with uncompromising performance
  • Incredible sporty exhaust sound, subtle when cruising
  • No drone with factory exhaust
  • Extra O2 bung are installed for use with wide-band sensors, if required
Fitment:
  • 2017-2020 Ford Raptor Ecoboost Gen2
Using the optional CEL eliminator greatly reduces the possibility of CEL coming on for cat efficiency code. This is not guaranteed to be 100% effective. Stage 2 downpipe-specific software tuning is required to avoid a check engine light.
