Stainless Works Exhaust Headers Mustang GT 5.0L 11+

The new 2011 Mustang GT comes with a brand new 5.0L engine boasting 412hp. There is no doubt that this is the most powerful engine for the GT from Ford. But like every factory engine, many restrictions are applied to improve gas mileage and meet emission standards. For those of us who are looking for pure power, these restrictions have to go.

Headers are among the best exhaust upgrades you can put on a performance vehicle. They are typically less restrictive and better designed with performance in mind. The Stainless Works exhaust headers are no exception. Constructed with 304 Stainless Steel, these 1 7/8" primary tubes will unlock even more performance for the new Mustang 5.0. The headers also feature a 3/8" flange and are finished off in a 3" slip fit collector with merge spikes.

The Stainless Works headers also have the option of coming with Race or high flow cat leads to further improve the exhaust flow. Please Select Below.
