Complete Performance Long Tube American Racing Headers for the 2011 and newer Ford Mustang V6
New from American Racing Headers is their complete longtube header system for the 2011-2012 Mustang with the 3.7L V6 featuring 1 3/4" Primaries and 2 1/2" x 2 1/2" collectors and x-pipe. These new 3.7L Mustang V6 motors make an impressive 300HP stock, but have so much more potential. A complete header system will increase exhaust flow in your Mustang and provide gains to HP and Torque across the RPM range, as well as provide an incredibly upgraded exhaust tone and volume. System will bolt up directly to the stock axle-back exhaust system, or will work in conjunction with any aftermarket axle-back exhaust.
Please note that installation of headers typically requires a tune for proper performance. The amount of air flow through the exhaust and performance changes the headers provide changes the manner in which the engine runs and for this reason a tune is advised. Non-Catted X-Pipe systems are intended only for off-road use. Please select your desired system from the drop-down menu below.

Complete Performance Long Tube Headers Package for the 2007 and newer Ford Mustang Shelby GT500
Arguably the most amazing hot rod to ever exit a Ford factory, the Shelby GT500 is here. With a mountain of horsepower just waiting to be unleashed, American Racing Headers’ bolt in long tube header systems can increase power and torque by as much as 40RWHP and 40RWTQ. Like all American Racing Headers’ systems, construction is all 304 S/S, flanges are 3/8" laser cut and collectors are merge style and incorporate scavenger spikes. X-pipes include 200 cell high flow metallic cats or can be ordered without cats. 1-3/4" primaries come standard. For high boost race applications, special order headers with 1-7/8" or 2" primaries are available as well.
The installation of an aftermarket header system alters the manner in which your engine runs so drastically, and changes performance so much that a custom tune is required with each installation. Please note that 1 7/8" and 2" header systems are only necessary for high-boost and highly modified applications, and will not run properly with a Mustang that is closer to stock. Please select your desired system from the drop-down menus below.
