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.
So you have spent over $1,000 upgrading your exhaust on your new car and it sounds great and you could not be happier. Until you walk behind your car and see your once shiny exhaust tips covered in soot and road grime. So you wipe them off and a week later they look just as bad as they did before. So this time you throw some wax on them, but that caused them to yellow and trap more dirt. You need a special polish for your exhaust tips that not only cleans the dirt off but seals them so they stay looking great. Our premium stainless steel polishing kit does just that. Our kit includes 2 large professional grade buffing compound sticks to bring back the shine on even the worse looking exhaust tips. A 4" buffing wheel to make cleaning your exhaust tips quick and easy. 2 special cloths for cleaning your exhaust tips at home and one to take along to shows to get your car ready for judging. And unlike other polishing kits, we also include a bottle of Simichrome Polish. Simichrome Polish puts a show winning shine on your exhaust tips and seals them so that they do not get stained like they used to anymore. We also include a set of photo detailed instructions to make cleaning your exhaust tips quick and easy.
