MagnaFlow 15987 System
Location: Ohio
Although I was told this system would not fit my 2006 Dodge RAM 3500 MEGA cab, 5.9 Cummins, I called Magnaflow and they confirmed that it would fit. I installed the system and it souonds GREAT!!! Nice power improvement and looks killer. The hardest part of the install was getting the old system off. I did have to modify the hangers for the center of the system but this was easily done. I used a 1/2" piece of rebar supported by the stock Dodge hangers and clamped this to the muffler hanger. Highly recommended!
