Very aggressive high pitched sound, it's as loud as you can get without going catless. Most importantly it doesn't produce any drone while cursing. It has unique full "X" design that no other manufacture utilizes. The build quality is impeccable, perhaps better than all the other systems out there, LucasFabs does some beautiful welding.

I had the car dynoed 443 HP to the hubs. The car is stock expect for the exhaust. The owner of the dyno showed me some graphs of stock gallardos on the same dyno and they were in the 400-410 range.

I love driving my car now, the sound is intoxicating.
