LS Engine Swap Exhaust Header for Custom Builds
Tailored for fitting an LS powerplant into a 1961 to 1962 Corvette, this LS swap exhaust header resolves common hot spot and flow restrictions by combining precise tube geometry with durable steel construction. Featuring 1.875 inch mandrel bent tube design and a ceramic coated finish, it deflects radiant heat away from the firewall and wiring harnesses while improving scavenging for more responsive throttle feel. Installation aligns with factory bosses on the Corvette frame requiring no cutting or welding, preserving critical space around steering linkages, coolant lines and accessory brackets from the initial bolt through final torque.
Precision Tube Geometry Enhancing Exhaust Scavenging
These headers feature 1.875 inch primary tubes with carefully tuned mandrel bends that guide gases away from the combustion chamber with minimal turbulence. Matching the tube diameter to the LS engine pulse pattern lowers backpressure and improves scavenging, sharpening throttle response across the rpm range. Smooth transitions through each bend maintain gas velocity for a consistent torque curve and quicker rev acceleration. Flanges are laser cut and jig welded to ensure perfect alignment with the cylinder head ports, promoting a leak free seal at startup. Positioning the assemblies close to the frame rails preserves underhood clearance for steering linkages and accessories.
Ceramic Coated Finish for Underhood Heat Control
A reflective ceramic coat forms a thermal barrier that deflects radiant heat away from the firewall, wiring harnesses and brake lines. By cutting underhood temperatures by up to fifty degrees Fahrenheit, the finish helps protect sensitive electronics and fluid hoses from premature wear. The surface seal also guards the steel against moisture and road debris, limiting corrosion over time. Retaining more exhaust heat inside the tubes energizes gas flow, which enhances scavenging efficiency on each power stroke. This coating option extends header life while supporting consistent engine performance on both road and track.
Robust Steel Construction for Lasting Reliability
Constructed from 16 gauge cold rolled steel, these headers resist cracking and distortion under repeated thermal cycles. The thicker wall absorbs unwanted vibration, yielding a quieter operation and a deeper exhaust tone. Steel's inherent rigidity maintains precise alignment with factory mounting bosses, preventing leaks and misalignment as temperatures rise and fall. Reinforced tubes and durable flange surfaces stand up to road impacts and abrasion under the rocker panels. This sturdy fabrication ensures the assembly retains its shape and performance for years of use.
Plug and Play Installation Preserves Engine Bay Space
The header kit bolts directly to the LS block using existing Corvette frame bosses, eliminating the need for cutting or welding to the chassis. Included gaskets and high quality bolts ensure a leak free seal from the very first fire up. The tubes are contoured to clear the steering box, coolant lines and alternator bracket, keeping critical pathways open for accessories and maintenance access. This straightforward process saves hours of labor and leaves the engine bay tidy and serviceable for future adjustments. Whether you are working on a street cruiser or track machine, the simple fitment delivers reliable results.
Engineered for a precise fit and reliable performance in your LS swap project, this header maintains underhood clearance and durability for miles of confident driving.
