well a trip to an exhaust shop and get a peice of exhaust pipe to fit in to the stock intake tube (here are pics to show what i mean
http://www.msnusers.com/aveopics/sho...nw?albumlist=2) and a hi-flow filter makes a quick and easy cold air intake and it only costs about 50$. you can get mufflers pretty cheap at pepboys for like 60-70$. also NGK iridium spark plugs help a bit. if you got a bit extra cash after that some good rubbers help your acceleration alot too. also i aint familiar with the car show language so please explain to me what "4 and the bust" means.
