i have a 99 cobra that is stock...i am in iraq right now and the money is building up...i figure i have about 3600$ to dedicate to my car when i return to the states...what do you think i should do. I am thinking 4.10's in the rear. These 2003 cobra's are tearing me up...help me get back into competition. I dont really wanna change the heads or cams for emitions reasons however an offroad x pipe is acceptable as it is easy to put the stock on back on. Thanks for your help...and never come to iraq...it sucks

oh and some drag radials
