Your 1999 to 2004 SVT Cobra is capable of producing a ton of power, but your factory exhaust system holds it back by clogging your Cobra's 4V motor with back pressure and general inefficiency, especially in the case of the supercharged 2003 to 2004 Terminator Cobras. Throwing on a few aftermarket exhaust components will help your mighty Cobra breathe a little easier and get you some excellent power gains on top of a brutal new exhaust note that will have everyone gawking in disbelief.
