I have the Berks and they sound great and I felt the diff. in power. they should give you some decent gains like 12 whp or more and Nismos even gain more than the the regular Z. I saw a thread of a Nismo gained around 19whp
don't have an idea if there is a diff in sound but I got mine with 500 shipped from Intense Power.
