1-7/8 Inch Ceramic Coated Mid-Length Headers for LS Engines
Swapping an LS engine into a 1988 to 1998 GM four wheel drive truck brings unique clearance and heat control demands that standard headers often cannot meet. These 1-7/8 inch ceramic coated mid length headers deliver precise port alignment and GM specific flanges to clear steering and suspension while smoothing exhaust pulses across the RPM band. They feature primaries sized to balance low speed torque with high RPM response and require no cutting or bending during install. Underhood temperatures fall noticeably as the ceramic shell keeps radiant heat inside the exhaust stream for improved component longevity.
Advanced Ceramic Shell for Heat Management
These headers use a ceramic finish that reflects radiant heat back into the exhaust stream, keeping underhood temperatures in check. By retaining warmth inside the tubes, exhaust gases flow faster and encounter less backpressure. The protective shell slows corrosion on the steel substrate and reduces thermal stress during repeated heat cycles. Cooler bay temps also safeguard wiring and intake components, helping maintain reliable performance across all driving conditions.
Optimized Primaries for Responsive Torque
The 1-7/8 inch primary tubes are sized to enhance low end grunt while still opening up at higher rpm. This diameter strikes a balance that sharpens throttle response and boosts horsepower without sacrificing everyday drivability. Drivers will notice smoother power delivery when accelerating from a stop or passing at highway speed. The design also contributes to better fuel economy by improving combustion efficiency across the rpm band.
Mid Length Tube Routing for Smooth Scavenging
Mid length geometry positions the tubes to create even exhaust pulse timing along the header array. This arrangement promotes consistent scavenging, which in turn yields a flatter torque curve from idle through redline. Because no cutting or bending is required for installation, the tubes maintain their engineered shape and length for optimal tuning. The result is a seamless power band that suits both street cruising and off road adventures.
Heavy Gauge Steel and Flange Seal Reliability
Built from thick gauge steel, these headers resist warping and cracking under high temperature stress. Mandrel bent tubes preserve a smooth internal surface, delivering unobstructed gas flow from the engine. The 3/8 inch flanges provide a sturdy mating surface that upholds a leak free seal even under extreme exhaust pressure. This robust construction ensures long term durability and consistent performance in rugged applications.
Built to precise specifications, these headers ensure a reliable fit and lasting durability.
