I just wanted to update this thread with before and after dragstrip results. I have a 2012 base sport 7AT and I went to the strip both times with the stock tires and at full weight with a near full tank of gas. Stock run was at 74 degrees out. Modded was 64 degrees out.
Stock was 13.445@103.43 and with the Exotic Speed cat back exhaust my car now runs 13.301@107.37
