YouTube - Fast Intentions Exhausts 370z
Interesting video: F.I. CBE with 12' res. + HFC and F.I. CBE with 18' resonators.
Listening it I was confused about first configuration: it sounds different from it
YouTube - 370Z Fast Intentions TDX Exhaust and Berk HFC and from what tony (Fast Intentions) posted with same configuration... why?
P.S. In Fast Intentions CBE, the carbon fiber option for final mufflers changes sound note in comparison with SS option?
