I have a 2017 Infiniti Q50S with an MBRP 3in catback exhaust. I just purchased the JB4 off a guy in here and I’m concerned that the mapping may have to be different due to the free-er flowing exhaust. Anyone have suggestions on a Level 6 map for my specific situation?
I have made a video on my custom cat-back exhaust for my 2015 q50. The total cost for my setup was just under $600 and it sounds amazing! I highly recommend going this route if you want a great sounding exhaust that doesn't break the bank.
