FlowTech Exhaust Shorty LT Headers for GM Trucks & SUVs

FlowTech Shorty LT Headers deliver the ideal combination of performance, quality, and value for Chevrolet and GMC truck and SUV owners. Engineered specifically for GM LT-based V8 platforms, these shorty headers are a direct bolt-on solution compatible with both 2WD and 4WD applications — making them a versatile performance upgrade across a wide range of full-size trucks and SUVs.

The shorty design retains the compact footprint of factory exhaust manifolds while significantly improving exhaust flow, unlocking gains in horsepower, torque, and throttle response across the entire RPM range. The OE-style ball-and-socket collector connects directly to the factory exhaust head pipe with no cutting or welding required, keeping installation straightforward for both DIY enthusiasts and professional installers alike.

Key Features:

• Mandrel-bent stainless steel tubing maintains consistent tube diameters for smooth, unrestricted exhaust flow and increased exhaust velocity
• Heavy-duty 16-gauge construction delivers long-lasting durability under extreme underhood temperatures
• TIG-welded, machined 3/8" header flanges provide a leak-free seal and maximum structural strength
• OE-style ball-and-socket collector connects directly to the factory exhaust head pipe — no cutting or welding required
• Direct bolt-on fitment to factory cylinder head mounting points for straightforward installation
• Emissions-compatible design on select applications accommodates factory OE emissions components and catalytic converters
• Multiple finish options available across the product line to suit different performance and underhood appearance preferences
• All necessary hardware and gaskets included for a complete, ready-to-install package

About FlowTech Exhaust: FlowTech Performance Exhaust was founded with the mission of delivering high-quality performance exhaust at exceptional value. Now part of the Holley Performance Products family, FlowTech continues to develop application-specific headers and exhaust systems engineered for late-model trucks and SUVs. These shorty headers pair well with cold air intakes, cat-back exhaust systems, and engine tuners to maximize the performance potential of your GM truck or SUV.

Important Notes: Ceramic-coated variants require several heat cycles to fully cure before withstanding extreme heat. Do not use header wraps on ceramic-coated units, as this may cause cracking or rusting and will void the warranty. Always verify emissions compliance for your specific application and region before purchase.
