I am looking to buy a X pipe for my 2012 Mustang GT, I have a corsa sport axleback currently on it now with a JLT intake. My questions is if I can a X pipe will it make it a little deeper and louder or smoother and quieter. I had seen people say it makes it louder but I contacted corsa on their X pipe and they said it actually makes it quieter and smoother. Which X pipe should I get?
