Quick question to Tony,

i have the 18 inch res + carbon kit and recently i have been hearing a weird frequency while i am cruising around 60 mph and 3000 rpm or less. is that normal and is there a way to fix? i cant say it is the resonators for sure but its hard to pin point it atm.

in no way i am trying to devalue the quality parts FI offers, i have the exhaust on me for over 20k miles and i love it
