| SSAutoChrome Inc 5.3L V8 SHORTY PERFORMANCE HEADERS |
| 2008-2013 CHEVY SILVERADO 1500 • GMC SIERRA 1500 |
| 304 STAINLESS STEEL • LS-BASED 5.3L V8 • DIRECT-FIT STYLE |
Upgrade your 2008-2013 Chevrolet Silverado 1500 or GMC Sierra 1500 5.3L V8 with the XS-POWER 304 Stainless Steel Shorty Performance Header Set.
Designed specifically for the popular GM 5.3L LS-based V8 platform, these headers replace the restrictive factory-style exhaust manifolds with mandrel-bent stainless primary tubes and performance-oriented merge collectors.
The shorty header design is engineered to improve exhaust flow and scavenging while maintaining excellent low-to-mid-range response — ideal for a street-driven Silverado or Sierra, daily driver, work truck, towing application or naturally aspirated performance build.
Unlike thin, low-cost headers, these are manufactured from 16-gauge 304 stainless steel with heavy-duty 3/8-inch laser-cut head flanges and TIG-welded joints for excellent durability.

Engine Platform: GM Small Block Gen III / Gen IV LS-Based 5.3L V8
Please verify your truck is equipped with the compatible 5.3L V8 engine and compare your original exhaust configuration before ordering. This listing is not intended as a universal LS swap header.
The collector uses an OE-style ball-and-socket connection designed to connect with the compatible factory exhaust head pipe.
This design makes these headers an excellent choice for truck owners looking for a performance-oriented exhaust manifold replacement without immediately building an entirely custom exhaust system.

Headers live in one of the harshest environments on your truck. Extreme heat, constant heat cycling and engine vibration can quickly expose weak tubing, thin flanges and poor welds.
That's why XS-POWER uses 16-gauge 304 stainless steel tubing combined with substantial 3/8-inch laser-cut head flanges.
The flange surfaces are flattened using a hydraulic press to provide a precise mating surface against the cylinder head and help achieve a reliable exhaust seal when properly installed.
Unlike crush-bent tubing that can become restricted through bends, mandrel-bent tubing is designed to maintain a more consistent internal diameter throughout the bend. This helps provide a smoother path for exhaust gases leaving the engine.
- Improved exhaust-flow potential
- Helps reduce exhaust restriction
- Improved exhaust scavenging potential
- Designed for excellent low-to-mid-range response
- Supports improved engine breathing
- Excellent upgrade for street-driven 5.3L trucks
- Works well as part of a complete intake and exhaust upgrade
- Great foundation for additional LS-based performance modifications
Actual horsepower and torque changes depend on the vehicle, ECU calibration, intake system, exhaust system and other modifications. No specific horsepower increase is guaranteed.
