Mustang Shelby GT500 Bassani Headers
Bassani Performance Headers for the 2007-2010 Mustang Shelby GT500
The 5.4L Supercharged V8 engine in the Mustang Shelby GT500s is an absolute monster of a powerhouse. Putting out 500+hp depending on the year model, it seems almost unimaginable that any part of that engine is restrictive, but it is. The header and exhaust that come stock with the Mustang GT500 suffocate the engine and, in doing so, sap much of its potential power and exhaust sound. By opening up the exhaust from the headers back for increased air flow, you'll be able to unleash an entirely new level of exhaust tonality and volume, as well tap in to untouched reserves of power for HP and Torque gains across the entire RPM range. New headers can make your GT500 feel and drive like an all-new car.
These headers are specifically designed to satisfy the exhaust breathing requirements of the 5.4L GT500 engine. The unique design of these Stainless Steel Longtube headers produces the widest torque band of any available header. All of these performance benefits are just the beginning, also. These headers are manufactured from the highest quality stainless steel components for incredible durability and efficient heat dispersion.
Headers are 1 3/4" and stepped to 1 7/8", 16g primary tubes, 3/8" thick laser-cut flange, with 3" collector. Available in a number of different configurations. When coupled with either the 5407R2 or 5407R3 Cat Adaptors, these headers will work with the Bassani Mustang GT500 Aft-Cat exhaust system to form a complete header back exhaust system, and one of the most powerful and aggressive exhaust set-ups on the planet for the Mustang GT500.
With any header install, slight exhaust placement modifications may be necessary. A custom proper tune is highly recommended with all header packages for any vehicle. Because of the change in air flow over the extremely restrictive stock exhaust, changing headers can cause lean running and thrown codes, and for this reason tunes are recommended; of course, a proper tune also provides the incredible benefit of unlocking all of your header systems potentials. Performance increases can go up as much as 30-35% when properly tuned. So, get the most out of your Mustang GT500 by installing a complete header package today!
