Fits Kooks Long Tube Headers and Improves Flow without a Bunch of Rasp
To maximize the power output of your Kooks long tube headers of choice, you're going to need a Y-pipe that lets your headers throw out as much horsepower and torque as possible. Kooks' Race Catted Y-pipe helps out by replacing your F150's restrictive factory catalytic converters with a pair of High-Flow Race cats that reduce back pressure in your exhaust system and gets your F150's or Raptor's 5.4L Triton V8 a bunch of extra horsepower and torque with the right custom tuning. Kooks' 2009 to 2010 F150 5.4L Race Catted Y-pipe is compatible with Kooks 1-5/8" Long Tube Headers
and will give your truck a great exhaust note on top of a bunch of extra power.
304 Stainless Steel Y-Pipe with 3" Diameter Tubing and High-Flow Cats
The Kooks Race Catted Y-pipe has extremely efficient flow, and maximizes your F150's power outputs without the rasp of an off-road Y-pipe or cat-delete system. The Kooks Off-Road Y-pipe is made out of 3" diameter tubing that's all carefully mandrel-bent to ensure excellent outflow with minimal restrictions. The Y-pipe comes standard with a pair of high-flowing Kooks "Race" cats, allowing your 5.4L truck to throw down big-time horsepower and torque without huge amounts of drone or rasp. The Y-pipe is made entirely out of 304 stainless steel and will resist corrosion and discoloration in practically any climate or application.
Fitment and Tuning: this Y-pipe will only fit 2009-2010 F150 5.4Ls with Kooks 1-5/8" Long Tube Headers. Custom tuning is required for the installation and operation of this Y-pipe.
