Chase,
Thinking ahead for the future. I have a 2SS RS M6 with the NPP dual performance exhaust. I like and want to keep the functionality of the NPP exhaust (not to mention the qual tips) but am consider upgrading to hi flow cats, and LT or shorties in the future. Was wondering what combinations you would recommend in that situation to get good sound and performance improvements?
You have not steered me wrong in the past so I would value your ideas.
Thanks,
