Description

The Stainless Works C48591 headers are engineered for the 1985-1991 L98 C4 Corvette. Constructed with 1 5/8" primary tubes and a robust 3/8" thick flange, these headers are designed to resist warping and ensure durability. The system includes a 2 1/2" slip joint collector and a matching 2 1/2" y-pipe, providing a smooth transition for exhaust flow. This header set comes equipped with AIR tubes and O2 bungs, facilitating integration with emissions systems and sensor monitoring. Please note that installation will require cutting and welding to connect to either the stock or an aftermarket exhaust system. Additionally, these headers are not for sale or street use in California and CARB states due to emissions regulations. Vehicle Fitment: Specifically designed for Chevrolet Corvette models from 1985 to 1991 equipped with the L98 Small Block engine.
