I am looking to replace the exhaust on my 98 Accord. What I really what is a dual exhaust. My problem is I am unable to find a good exhaust for my car. If anyone know where I can find a quality exhaust that is not overly loud but good looking and helps with the performance please let me know. Or if anyone could tell me if a cat-back exhaust for the V-6 accord would work on the four cylinder that would be great too. Thanks for the help.  

I would recommend the greddy sp2, seems like what you are looking for. Though its kind of deep on the throttle it is definitely not too loud and it maintains a stock(ish) look.  

RS-R ExMag, street version, rated the quietest exhaust system with the performance edge.  I don't know if RS-R made exhaust for your specific car.  You can search for it.  GL
