| well with the lly and lbz they have a varible vane turbo which makes it cound more like a jet than that deep growl of the older lb7's i have the newer lbz eith efi live and can take care of that jet sound at idle to make it sound more live a V8 thats idleing... but mbrp makes a good quality product and would sugest either them or silverline.
