Proposition65 Warning: Cancer and Reproductive Harm

Kooks 13723400 – 3″ Stainless‑Steel H.O. GREEN Catted Connection Pipes for 2023–25 Raptor R 5.2L

Designed for the Ford F‑150 Raptor R (5.2L Predator V8, supercharged, four‑valve) from 2023 through 2025, this 3″ stainless‑steel H.O. GREEN Catted Connection Pipes set provides a seamless OEM exhaust connection from Kooks headers. Made from high‑grade T304 stainless steel, it offers durability, extreme heat resistance, and long‑lasting corrosion protection. Backed by Kooks’ limited lifetime warranty to the original purchaser, this is a proven, race‑tested upgrade. 

Key Features

  • 3″ diameter precisely matched to OEM exhaust system

  • H.O. GREEN catalyst coating for higher precious‑metal cell count and thermal tolerance

  • Connects directly from Kooks long‑tube headers to the stock OEM exhaust system

  • 100% designed, manufactured, and bench‑tested in the USA by Kooks, with over 50 years of high‐performance experience 

Benefits

  • Reliability under stress: Coated catalyst withstands elevated temperatures found in high‑output, forced‑induction applications

  • Long‑term value: Limited lifetime warranty covers workmanship and materials defects for original purchaser 

  • Track and race proven: Designed and tested in motorsports environments (NHRA, NASCAR, SCCA, etc.) to perform under real competition

  • Peace of mind: Compatible only with racing or off‑road use; not legal in California, but approved for EPA 49‑state racing use 

Product Specifications

  • Size: 3 in (outer diameter), designed to mate precisely with OEM exhaust

  • Material: Aircraft‑grade T304 stainless steel, polished stainless finish

  • Color/Finish: Natural stainless steel

  • Catalyst: H.O. GREEN catted connection with high precious metal content

  • Hardware: Includes flanges, bolts, gaskets, O₂ sensor extensions

  • Warranty: Limited lifetime warranty to original purchaser

Install Difficulty Level
Installation is straightforward for anyone familiar with bolt‐on exhaust work. The kit includes all necessary hardware and O₂ sensor extensions. Many customers report installation completion in as little as 1 hour when paired with Kooks headers—a clean, no‑weld process that drops right into place.

Vehicle Fitment
This connection pipe set fits the Ford F‑150 Raptor R equipped with the 5.2 L supercharged Predator V8 (4‑valve) produced for model years 2023, 2024, and 2025. It must be used with Kooks long‑tube headers and is not compatible with other header brands.
