I have an 05 with the newer Larini and stock cats and it sounds awesome although I have really only heard it myself from inside the car.... So I say go with the Larini.... or, the LOC, you are not 100% correct on the LOC sound, a bunch of us went out to the dragstrip and there was a Gallardo with a LOC exhaust and it couldn't have sounded more whiney high-pitched F1 sounding... Just sick!!!!!! I don't recall what it sounded like at lower RPM,s but that is a definite front runner as far as exhaust goes, IMO
