1968-1972 A-Body X-Body LS Mid-Length Ceramic Coated Headers
Fitting an LS engine into a 1968 through 1972 A Body or X Body chassis brings tight clearance requirements and high underhood temperatures that stock manifolds struggle to manage. These ceramic coated mid length headers employ 1.875 inch primary tubes coupled with robust flanges machined at three eighths inch thickness for a leak resistant fit within factory frame rails. The silver coating acts as a thermal shield to trap heat inside the headers, lowering engine bay temperature and protecting nearby wiring and components. By delivering consistent scavenging across the rev range, they produce a deep, classic exhaust tone while smoothing torque delivery in every gear.
Precision Steel Structure with Thick Flange Design
The core of these mid length headers is heavy gauge steel tubing paired with flanges machined to a full three eighths inch thickness. This stout flange dimension prevents warping under repeated heat cycles and maintains consistent gasket compression for a leak free seal against the cylinder head. The rigid steel assembly keeps tubes aligned even when subjected to engine movement and road vibration, simplifying installation and reducing the need for realignment during maintenance. By resisting deformation and retaining its shape, the header ensures dependable performance and quieter operation over many seasons of use.
Ceramic Coating as an Efficient Thermal Barrier
Each primary tube and collector section receives a tough silver ceramic finish that acts as a high temperature barrier. By reflecting radiant heat back into the exhaust gases, the coating lowers under hood temperatures by as much as fifty degrees Fahrenheit, which helps protect hoses, wiring and intake components from premature aging. The ceramic layer also resists corrosion and surface pitting, keeping the header looking sharp even after exposure to moisture and road salt. Cleanup after spirited driving or track events is easier as grime and oil wipe off without scrubbing.
Flow Optimized Tube Configuration for Enhanced Scavenging
At the heart of the design are 1.875 inch diameter primary tubes laid out in a careful equal length pattern to maximize exhaust gas velocity. Equal length routing balances pressure pulses from each cylinder, which improves scavenging efficiency across the rev range and helps eliminate midrange flat spots. The result is stronger torque down low, smoother power delivery at cruise and noticeable horsepower gains at high engine speed. A byproduct of this tuned flow is a deep, muscular exhaust note that underscores the character of an LS engine swap.
Engineered Fitment for A Body and X Body Chassis
These headers are shaped to clear frame rails, suspension links and steering shafts in 1968 through 1972 A Body and X Body frames without any cutting or welding. They bolt directly to the stock exhaust ports using standard gaskets and the supplied hardware, preserving factory ride height and under hood space. The mid length layout offers the right balance of clearance and tube length to optimize performance without trimming motor mounts or crossmembers. This dedicated fitment cuts installation time and lets you focus on tuning rather than fabrication.
Built to fit precisely and resist heat cycling, these headers provide reliable performance for your LS swap.
