So, what exaclty have you done to the exhaust system? No cats at all now and free flowing axle back? Meaning catless DPs, catless midpipe and free flowing axleback? Just trying to clarify what you did exactly. Also, are both dyno runs on the same software (beta 1) or is Cobb tuning the software for your new setup?
