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.
I'm currently looking to purchase exhaust and low down pipes for my q50 but I cant really decide, maybe you guys can help my out.
I'm looking at MRBP exhaust, Greddy exhaust, ark exhaust , and fast intentions cat back exhaust.
Would it be good to go 3inch mrbp or 2.5 to 3inchs, or...
