Kooks Headers
Kooks Headers 2015-2026 Ford Mustang 5.0L Resonator Delete H-Pipe Kit (11513500)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2026 Ford Mustang GT, Bullitt, Mach 1, and Dark Horse models (5.0L).
Unlock a deeper, more aggressive exhaust note and improve flow on your Coyote-powered Mustang with the Kooks Headers Resonator Delete H-Pipe Kit. This kit is engineered to replace the bulky and restrictive factory resonator, reducing backpressure and shedding weight from the exhaust system. The H-pipe design is specifically chosen to provide that classic, low-frequency muscle car growl while balancing exhaust pulses between cylinder banks.
Built for longevity and performance, this kit is handcrafted in the USA using T304 stainless steel to resist corrosion and handle the high-heat cycles of performance driving. It is designed to install into the factory exhaust path for a clean, precision fit that maintains proper clearances under the chassis.
- Replaces the restrictive OEM resonator for improved exhaust flow and sound
- Constructed from high-quality T304 stainless steel for maximum durability
- Classic H-pipe configuration delivers a deep, resonant exhaust tone
- Handcrafted and dyno-tested for optimized performance
- Includes all necessary hardware for a direct installation into the factory system
- Limited lifetime warranty for the original purchaser
- Manufacturer Part Number: 11513500
