Hmm...mine sounds just fine, especially at idle. It rasps when it's cold, but what doesn't. The only thing I don't like is the fact that it rasps when under load...atleast when you're doing some spirited driving. Although, most of the people i've raced say it souds good....I'll replace the exhaust eventually. The stupid mechanic gave me a freaking exhaust leak...or so I think, there's a whistling noise I hear when I get around 3-4krpm.
