1-7/8" Stainless Steel Long Tube Headers

The Kooks 1-7/8" Stainless Steel Long Tube Headers are engineered for the 2015-2026 Ford Mustang GT 5.0L 4V. These headers are crafted from durable 304 stainless steel, ensuring longevity and resistance to corrosion. They feature 3/8" thick laser-cut flanges for a precise fit and 1-7/8" mandrel-bent primaries designed to optimize exhaust flow. Included in the kit are 755392 gaskets, specific oxygen sensor extension harnesses (CAS-105979 for 2015-2017 models and CAS-109677-8 for 2018+ models), and necessary bolt kits (BK109 & BK114) for installation. Please note that these headers require Kooks Front Connection pipes and either OEM Adapters (11513000) or an X-Pipe / H-Pipe exhaust system for full integration. These headers are also available as part of complete Header and Connection Kits, such as part numbers 1151H432 & 1151H442. Built to order in North Carolina, these headers have an estimated ship window of 4-6 weeks.
