hey guys, my friend has a 240sx and he is lookin for an exhaust for his car. its a 1990 wit a ka24de swap in it. and he has a ricer muffle on it (the way he bought it) and he needs it gone, and wants to buy an exhaust for cheap. around $200 - $300. and if there isn't really a good exhaust system that would fit his car for around that price, than what is a good muffler for cheap. he needs sumthin to sound nice, and he wants power. so any1 wit a 240sx know what exhaust would be nice to fit on his 240sx?
