Love the Dynomax

I bought a MF Stainless Steel cat back exhaust. The first one had the flange welded on crooked, the second one did too but not as bad and I got it to work. Tip was too shiny and bent down. Drone in cab was crazy. Sold MF after 2 weeks and bought the Dynomax, absolutely love it. Just a bit louder than stock but hardly noticeable, nice easy fit, brushed SS tip that exits straight back so it looks fabulous. It is Aluminized not SS so it won't last like the MF but at half the price I can buy another one in 8 years and still be ahead.
