Can't beat the rumble of a V8, Mine is the ute in my avatar, 260 KW, June 2006 build date, 19,000 ks on the clock, Extractors, 2 1/2 inch stainless exhaust with hi flow cats, Big Mouth Cold Air Induction Kit, K&N hi flow air filter and a C.A.P.A Ford Flash Tuner, all up a lot more output than stock, but have not had it on the Dyno yet. Next is the Yella Terra (Whipple) Supercharger.
Highly recommend the exhaust and cold air intake upgrades, lot of extra bank for reasonable outlay.
