I ordered the kartboy exhaust hangers because my aftermarket muffler seems to move too much, but when going under my car, I could only find one hanger currently holding my muffler. They come in a set of 4. Should there be three other places I need to replace? thanks

 

There are two right by the muffler, one on right, on further back on left. The other two are located right up by the second cat. The hangers are all black rubber stock, so they may be difficult to see if there is not sufficient light.

 

good choice, but I have heard that Kartboy Exhaust Hangers make muffler stay too close to rear bumper...
