Very nice Scott, Those Z's are a nice car. A buddy of mine has on '03 Track Model that i play mechanic for the upgrades. So far we have added a larger plenum, nismo CAI, Nismo catback, Nismo strut bar, technosquare ecu reflash. he just bought a greddy TT kit and has sold the catback today. So I have some wrench time coming and then hook him up with Marco at Billet Design for a custom 3" 304 stainless, mandrel bent exhaust.
