The Stainless Works CTTHCAT is a long tube header kit engineered for the 2007–2014 Chevy Tahoe and GMC Yukon LT. Featuring 1-3/4" primary tubes and 2-1/2" collectors, these headers are designed to improve exhaust scavenging, increase airflow, and deliver meaningful performance gains over factory exhaust manifolds.
