This is my first sports car and first exhaust purchase. I have a 2019 ss and I bought the borla atak cat back with npp dual mode system for $2700. I noticed in the description that it does not come with the valves and that I would have to reuse my stock valves and thought ok no big deal. Got the exhaust in the mail and unboxed everything I see no way to reuse my stock valves. Is there something else I need to purchase? The sales person at American muscle said I would have everything I needed with that system
