Get Huge Power Increases in a Complete Headers Package with Flawless Quality

Sometimes, you don't have to sacrifice quality and massive power gains, and this Stainless Works Long Tube Headers and X-Pipe Package has all of the awesome and high-quality hardware you need to give your aggressive 2011 to 2014 Mustang GT 5.0L build a big increase in horsepower and torque, especially if it's already supercharged. The Stainless Works Headers Package replaces the most inefficient and restrictive components of your Pony's factory exhaust system, leading to an excellent increase in horsepower and torque output at your rear wheels. The Stainless Works headers package comes complete with a pair of immensely powerful long tube headers that are paired up a catted mid-pipe so that your Mustang's 5.0L Coyote V8 can breathe and function to its full potential, make impressive power gains, and add one of the most ferocious sounds out there to your tough Mustang.

Large-Diameter Primary Tubes with Velocity-Spike Collectors

The Stainless Works long tube headers included in this package were designed and constructed to maximize exhaust outflow efficiency and reduce the back pressure in your 5.0L V8's cylinders. The headers are built around a set of massive, 7/8" diameter primary tubes that are each precisely mandrel-bent to ensure nearly restrictionless exhaust flow from your motor's exhaust ports. The primary tubes drop down into a 3" collector assembly that contains a specially-designed merge collector that allows for improved exhaust scavenging and less turbulence as exhaust gasses move through into the mid-pipe. The headers come standard with a 3/8" thick flange for connecting to your Mustang's engine and 3" slip-fit connectors that make it easy to install your choice of X-pipe included in this kit. The headers are made out of high-quality 304 stainless steel which allows them to resist corrosion in just about any climate or application.

Included X-Pipe with High-Flow Cats

The X-pipe that Stainless Works Includes in this kit works with the long tube headers to help your Pony get as much power as it can out its heavily-modified exhaust system. This system comes with a catted X-Pipe. The catted version of the X-pipe features a pair of high-flow catalytic converters that quiet up rasp and drone at the expense of some power and an increased price tag. Both versions of the X-pipe are made using 3" diameter, mandrel-bent tubing which keeps restrictions extremely low. Just like the headers, the X-pipe is manufactured out of 304 stainless steel which keeps it looking and functioning perfectly for thousands upon thousands of miles. The X-pipe features Stainless Works Performance Connect system that can only work with Stainless Works Performance Connect cat-back kits.

Choice of Finish

The entire kit comes with different options for finish so that you can get the look or additional protection and performance your system needs to survive the toughest Mustang applications out there. The kit comes standard with basic, natural milled 304 stainless steel finish at no additional cost. The kit can be upgraded to a bright, polished finish to add an awesome and old-school look to your Mustang's engine bay and undercarriage without a ton of hassles. The kit can also come with a ceramic Thermal Coating that helps keep temperatures down to increase performance while adding a great look to your Stainless Works Exhaust System. Please select a finish option from our drop-down menu above.
