Aftermarket muffler that I have drilled a dual port on top and added a screen with deflector, then I also added another screen for the front cover plate. This for 1 ported muffler (some pictures show 3 mufflers) that is only for you to see all angles of what the mufflers look like. Order as many as you would like. 49.99$ each. THANKS!
