Now if I've run about 37000 miles with NO dampening at all (UR UDP), why do you think you need to pay alot of money for even more dampening than whats in the stock unit? Higher rpm's doesn't really cut it either, as the harmonics point (ask judge for number) is much lower in the rpm band. What it comes down to IMHO is a $/hp call.
Me? - obviously I'm taking the informed risk of blowing my engine all to h@ll by running my evil UR UDP - but that's just me
