Even though Ford's 1999 to 2004 SVT Cobra's are powerful, mean editions of the Mustang, they don't really sound like it. Aftermarket cat-back exhausts for the 1999 to 2004 SVT Cobras fix that problem and provide a huge, roaring growl and slight gains in power. Cat-backs replace your factory mufflers, kickover tubes, and exhaust tips with louder, more efficient, and better-looking designs that get you a mean exhaust note. Bring out the roar of your 4V 4.6L V8 with a Cobra cat-back exhaust today. If you want more power, then take a look at our selection of 1999-2004 Cobra header and mid-pipe packages that are practically free of back pressure and restrictions. For even better gains, take a look at our 2003-2004 Cobra supercharger pulleys, Cobra intake upgrades, and 4.6L 4V tuning options.
