Kooks 1-3/4-Inch Long Tube Headers with Catted H-Pipe (12-13 Mustang BOSS 302)Find parts that fit my vehicle

Premium Performance Header System. The Kooks Long‑Tube Header & Catted H‑Pipe Kit delivers enhanced exhaust scavenging and horsepower gains for the 2012–2013 Ford Mustang Boss 302. These headers use 1‑3/4″ mandrel‑bent primaries to improve flow, while the catted H‑pipe ensures street‑legal emissions and a rich exhaust tone. They are essential for enthusiasts seeking both performance and compliance.

Construction And Appearance. Built from high‑grade 304 stainless steel, the Kooks Long‑Tube Header and Catted H‑Pipe Kit features durable natural‑finish tubing with precision TIG welding. The flanges are thick and laser‑cut to ensure excellent sealing and alignment. The included H‑pipe matches OEM dimensions (3 main to 2‑3/4-inch side pipes) and completes the polished stainless ensemble.

Installation. Installation requires moderate mechanical skill; engine movement is needed (or K‑member removal) along with basic hand tools. You’ll need to remove the stock manifolds, replace studs with included hardware, and torque to specs—no specialty fabrication required.

Warranty. Backed by Kooks’ limited lifetime warranty to the original purchaser.

Application. This Kooks Long‑Tube Header With Catted H‑Pipe fits 2012–2013 Ford Mustang Boss 302 models.
