What exhuast system is not only the best in porformace, but also doesn't a car sound like ****. Something that sounds almost close to stock.

 

Alot of ppl will recommend the Apexi World Sport 2 or like an ES Oval. Those are as quiet as you can get in a 2.5'' application.

I personally like a louder car. I have a Tanabe Super Racing Medallion with a 22'' resonator then a 14'' resonator and it's still really loud.

Here's a vid of how it sounds. This isn't my car, though very similar.

RS*R ex-mag

 

If you want quiet I doubt you will be getting max pergormance. In most cases you will have to make a choice of one or the other. Perhaps there are some out there that are quiet yet still flow extermely well but I am not aware of those.

For quiet I would recomend A'Pexi WS2 or RS*R Ex-Mag like mentioned above.
