That sounds super loud! Awesome stuff! Does the cabin sound get too overbearing? I find in my 4c with sports exhaust it can be a little tiring with how loud it can get in the cabin.

Does this mean the i4 ECU is now officially cracked? Does this pave the way to higher performance maps being developed soon?
