About a week ago I bought an '08 IS350 and I'm already thinking about what to do to it. I wouldn't mind making it a little bit faster. The thing is, I don't want to make it a loud car. Considering it's not really a "muscle car" and it's more of a "luxury car" I'd like to keep it nice and quite. Again I'm not looking for hundreds of horsepower.

Anybody?? Anything??

 

uh, wrong forum...
