I too put a Tubi on my 04 Gallardo. I waited and kept thinking that I would keep it stock but after a few months of ownership I changed my mind and installed it and I couldn't be happier. As a friend of mine said "it now sounds like a 500hp car". IMO you made the correct decision and the price you paid it what i paid so don't worry about what other systems can cost, the Tubi is first rate. Good Luck!
