I have a 90 civic si and my current exhaust system is broken. I am looking for a replacement, i dont want an exhaust system that will annoy me or will get the attention of cops. I need and exhaust that is not loud at all but not as quiet as the stock replacement either, money is no issue. is the flowmaster a good choice? is it too loud? im open to all coments
