What to modify?!

I have about 1,000$ that I would like to invest into my 00' v6 obviously vert mustang. I was thinking of an intake system and dual exhaust. Problem is I see and hear alot of things. Im not exactly sure on any good sites as it seems harder to find v6 mods then the v8 mods Anyways I would like to hear peoples advice. What to purchase for a intake system and a new exhaust system. What kind of exhaust and if you know any sites to buy off. So if yall can gimme a hand here id love it. Ive seen some intake and exhaust's but im not sure what I need. Im still learning things so its easier for people to just give me there advice and I can compare what I would like to that Also if there are other modificiations that I can possibly do my self which a tool set and no welding hehe. What other bolt on mods are good that might boost the performace of my car. I dont really care if the car sounds bad ass because id rather have it perform badass So everyones feedback is defintly welcome. Your advice on intake,exhaust ect i dont really know much and wanna learn all i can. So with that said please help guyz!

What kind of gears do you recommend and any websites that sell them cheap? O ya I have only 1 tire that grips which is the right tire. How do I solve that problem? I know its like trac-loc but thats GM i thought or something like that. But I want both tires to grip better seeing as I live in New England and would like both tires for better traction and i figured both tires gripping is better for putting the power to the pavement. Im not exactly sure which gears would be better for power and also how do I solve this 1 tire traction problem!
