It will be loud as hell but annoying is up to your definition lol. I have the same set up only I have long tubes as well with my off road x. It screams and has serious *** drone on the interstate. But I personally like that ****. I'e always been a fan of the metal or tin style tone of the flows. To me the 2vs can carry a similar push rod tone when paired with flows. Gives the old school this is what a mustang should sound like sound. You will get a million opinions but I've always liked it. When I head to work tomo I will see about posting a video I it helps.
