more horse and a meaner sound

I got a 87 trans am with a stock 350 in it. In about 1 month i have a cruise i have to go to what can i do that is cheap and easy to give me more horse in that amount of time? also what kind of exhaust is recomended i want a low rumble at idle and a mean ass sound when take off. and last but not least how much would it cost me to get it dynomaxed and how much horse would it add. and how much roughly do i have now?

Well it sounds as if you want a little more noticable uumpft, and some exhaust note right?

Get an exhaust system. Some headers, and a cat back system. Me personally, for the money, Edelbrock TES is just fine on both accounts.

what suggested exhaust i heard magna flow

As stated, to each their own, I'm just saying, bang for the buck over stock, the TES headers and American Thunder systems are cheap, and improve flow greatly. Also while allowing the little extra cash for say a larger rear end gearing, all for the same price as if you went and bought a whole system from someone else is all i'm saying.

definately go with magnaflow
