1-3/4" Stainless Steel Long Tube Headers

The Kooks 1-3/4" x 3" Stainless Steel Long Tube Headers are engineered for enhanced performance on 1999-2013 GM 1500 Series Trucks and 2000-2014 SUVs equipped with 4.8L, 5.3L, 6.0L, or 6.2L engines. The 1-3/4" mandrel-bent primary tubes are designed to optimize exhaust flow, contributing to improved engine performance. Installation includes all necessary hardware, such as PY-8024-AL gaskets and BK110 header bolt kits. However, these headers are not a direct bolt-on to the factory exhaust system and necessitate the use of a Kooks Y-pipe or custom dual exhaust connections. The product is built to order in North Carolina with an estimated ship window of 4-6 weeks.
