The 4.6L V8 engine in the Mustang GT requires a great deal of airflow to really get everything out of the engine, and the stock headers and exhaust just don't provide that power. These after-market Bassani headers are brilliantly designed to open up your engine exhaust flow and provide that extra power to your Mustang engine. By increasing air flow, after-market Bassani headers will provide increases to HP and Torque across the RPM band, as well as provide your Mustang GT with a louder and powerful exhaust tone. These benefits all come thanks to Bassani's forward-thinking R&D, and their manufacturing process which uses the highest quality stainless steel materials.
These headers are specifically designed to satisfy the exhaust breathing requirements of the Mustang 4.6L 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 5/8", 14g primary tubes, 3/8" thick laser-cut flange, with 2 1/2" 4 in to 1 collectors. Available in a number of different configurations. If you want to stick with the stock mufflers, these headers can also be ordered with Bassani's patented power crossover X-pipe. This X-Pipe will bring the complete header package back to where the axle-back exhaust will meet, forming a complete and true Long Tube package. Can be coupled with the Bassani Mustang GT Aft-Cat system and Catted Connection pipes 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 GT.
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 GT by installing a complete header package today!
Please select all of your header package options from the drop-down menus below.
