Best Exhaust for the $$$

Between Calmini and Gibson, which cat-back is the best sounding and performing for the green?

Any other companies which you believe would be better than these please feel free to put in your 2 cents.

I haven't heard the Calmini, but my Gibson sounds sweet! One of the nice things about the Gibson too is that it concentrates the sound at the tailpipe so the increase in cabin noise is minimal unless you roll the windows down. :D It emits a low throaty growl at idle and maintains a nice growl all through the rev range without ever getting buzzy.

One important thing though. You need to get a high flow air intake like the K&N FIPK kit to go with it to really make it come to life.

I've got the K&N FIPK but I wanna open up the other end.

What about the Borla?

Haven't read much about it but seems like quality equipment.
