I have been contemplating doing the basic pulley swap on my '11 cause the stock one is waaaay to quite compared to my pullied Terminator, but my question is, is it safe to keep the stock exhaust? I really like the way the stock exhaust sounds, so I really wanna keep it if it won't really matter too much. I'm not worried about losing horsepower by not having aftermarket exhaust, I just don't wanna hurt the motor or anything :banana:
