Muffler, Black
Only one with the dual inlet / dual outlet setup
I own a 2004 Cadillac Escalade with the 6.0 engine which has the dual inlet / dual outlet muffler setup from the factory. I wanted the 40 series, but the 40 series doesn't come in dual inlet / dual outlet setup. But the 50 series Big Block muffler does. So, I was forced to get the 50 series. Everyone tells me that the 50 series is the better choice for a refined suv such as the Caddy, because it is loud, but not offensive as the 40 series. They say, " it goes with the truck"
