Shorty Exhaust Header

The JBA 1840S-4JS is a performance-oriented shorty exhaust header engineered to significantly improve the power and efficiency of your 1988-1995 or 2002-2003 Chevrolet S10 equipped with the 4.3L V6 engine and 2-wheel drive. Constructed from durable stainless steel, these headers feature mandrel-bent tubing for optimal exhaust flow. The primary tubing diameter is 1.625 inches, leading to a 2.5-inch collector port. This header is finished with a metallic ceramic coating in grey with a semi-gloss sheen, providing both aesthetic appeal and heat resistance. It comes equipped with factory-style emission connections, a 3/8" thick flange, and includes both gasket/seal and mounting hardware for a professional, no-leak installation. The tube wall thickness is 0.059 inches, and it features an oxygen sensor port. Important fitment information indicates that header applications are based on original engine and cylinder head port centerlines. Raised port cylinder heads may cause installation issues. The product also carries a C.A.R.B. EO Number: D-57-48.
