To me I did detect an exhaust leak and possibly some valve noise but I'm no expert. I'd make sure the whole system is leak free from the J-tubes on down and adjust the valves to make sure the lash is set properly. If none of that works then it may need a new exhaust.
The Tri-Mil Exhaust came stock on almost all of the cars built by VS on their stock size engines. They are very quiet and not a lot of money.
