Either one would probably work, but the tip would probably be easier. Based on that other pic you attached, the tips looked pretty long. So if you attach the tip to your stock muffler, it may end up sticking out further than you want. But I dunno...you'd have to measure it. Same with the muffler. You are in a better position to find this out than us...unless someone here also has a access to this car like you do.
