So got a good chance to test it out, the v2 crackles are very noticeable on the stock exhaust, and Im not sure if they be too much when I get my catback on or not but well see.... Also just something to note, I assume this is caused by the crackles but upon taking your foot off the throttle the car now engine brakes harder (again I assume because the crackles) and almost jerks you forward a little harder every time your not easy letting off the gas as the crackles start. Power feels great and smooth as always, havent gotten a chance to test Cobb TC since its rainy here too.
