1-7/8in Ceramic Coated Mid-Length LS Headers for A-Body
Swapping an LS powerplant into a 1973-1977 A-Body car puts a premium on exhaust parts that fit snugly and pave the way for steady flow and these 1973-1977 A-Body LS 1.875 inch ceramic coated headers answer the call with exact flange alignment. Built from stainless steel and finished in ceramic to resist underhood heat and corrosion, they maintain consistent performance over long runs. Installation stays simple with thick flanges sealed against leaks and all required gaskets and hardware included, so you can focus on fine tuning throttle response and the classic muscle tone.
Exact Fitment for 1973 to 1977 A Body LS Engine Conversions
The design centers on perfect alignment of the 1 7/8 inch tubes with cylinder head ports on GM A Body models built from 1973 to 1977. Each flange measures 3/8 inch thick to maintain flat sealing surfaces under extreme heat cycles and prevent warping. This precision fit eliminates the need for header spacers or grinding, saving valuable time during swap projects. By holding the correct distance from the steering linkage and frame rails, these headers ensure proper clearance while allowing room for auxiliary accessories.
Premium Steel Construction with Ceramic Coating
Built entirely from stainless steel, these headers resist corrosion in harsh underhood environments and maintain structural integrity at elevated temperatures. The ceramic coated finish reflects radiant heat away from sensitive components, enhancing intake efficiency and reducing engine bay temperatures. This effective heat management lowers underhood heat by up to 100 degrees compared to bare steel parts and helps preserve wiring and hoses. The coating also wards off rust caused by road salt and moisture in damp conditions.
Optimized Flow Characteristics for Improved Torque and Sound
The 1 7/8 inch mid length tubes are sized to match the LS engine torque curve, delivering strong low rpm response and enhanced top end power. Smooth mandrel bends ensure uninterrupted exhaust flow and minimize pressure points that can sap horsepower. Precisely tuned merge collectors blend exhaust pulses for a rich, throaty muscle tone without creating drone on the highway. This balance of flow and sound captures the essence of a classic muscle car with modern performance delivery.
Comprehensive Hardware Kit for Simple Installation
Every set ships with factory style gaskets, bolts, dowels, and a full instruction guide to streamline the swap on your A Body chassis. With basic hand tools you can bolt these headers into place in a weekend, without trimming the steering or modifying frame rails. The leak free design relies on perfectly matched flanges and quality hardware that hold torque through repeated heat cycles. No extra trips for missing parts means you can focus on dialing in throttle response and final driveline tuning.
