When I had it done ,I had a completely stock exhaust. I had a x pipe added and the rear resonators removed the same day they installed the cut outs and what you heard on the you tube clip are the results of that.
I had headers and high flows done after. It changed the sound up front in the engine bay but that's the headers sound but in my opinion didn't change much in the rear. The sound from the cut outs over powers the sound of the headers up front.
Sound is subjective and most video clips doesn't do the actual sound of the exhaust justice. Better to hear cars in person. So as for what you want specificly , I'm not sure.
