Nothing beats the pure beauty of the Ferrari (or any exotic ftm.) but so saying to the Bmer haters here, the mods were MINIMAL for power gains; Gaining 15 hp at best , and the Diff would only gain applicable torque, while slowing him down between shifts (ask how I know).
I'm planning to upgrade to this system in the near future, What exhaust are you running? Sounds deeper than factory? Or is that from the System?
