Well I finally got around to installing a Quicksilver exhaust in my '05 Gallardo. As requested by some of you I have written this up in detail for others that may be considering doing the same thing at:-

I have to say the Quicksilver is better than ite OEM Lamborghini one. I was hoping for a bit more sound. Anyway I will try it for a few months.

does it sound any better?

mon i just put the qs system in my murci and its loud as sh--- !!! did you install the cat by pass ? Also how do you feel the car responds now performance wise , feel any different ? I am happy with mine and definitly recomend it .

There are two Quicksilver exhaust systems for the Gallardo. I have used both and have written it up on lamboweb.com. I did not use a cat bypass, but the "supersport" is loud and does get to you after time. In the end I settled for the simple "sport" system.
