I'm taking the Larini Sports Exhaust out of my 07' Gallardo Spyder. Although it's the best sounding exhaust on the planet (in my opinion), it makes the car a pig at low RPMs terrible throttle response). After driving it, the dealer has agreed to give me a full refund.

I'm now thinking of trying a QuickSilver system. They make 2 for the 07' Spyder - the Sports and the Titanium SuperSports. Has anyone tried these on an 06' or 07' Spyder or Coupe (05' and earlier is a different system). If so, how do they sound and how is the throttle response?

Any info would be greatly appreciated.
