I too have the Dinan Mufflers on my 4.4 and like them but i do agree they are expensive. And also the exhaust tips are not chrome they are stainless steel and part of the muffler not just a slip on tip. But i hate the fact you have to cut the old one off and slip on the new muffler. I recently damaged my mufflers and had to buy new oem mufflers and dinan mufflers. i just think its stupid but all after market companies do this know.
