According to my technical contact at MagnaFlow, when installing the 20-inch Stainless Clamp-On Exhaust tip # MF35187, you will not have to cut the factory exhaust on your 2013 Dodge Ram 3500.
This part simply clamps on over your existing 4-inch diameter exhaust pipe using the welded-on band clamp.
This tailpipe tip does have a lifetime warranty from MagnaFlow. view full answer...
The Magnaflow # MF35239 exhaust tip isn't a vehicle-specific item, it'll fit on any 5 inch diameter tailpipe. If that's the outside diameter of your exhaust pipe at the exit, this exhaust tip would work great for you. The tip is constructed from stainless steel for corrosion resistance and features a hardened enamel coating for superior durability. The exhaust tip is a clamp-on application with no welding required for installation. view full answer...
You'll have to measure the other diameter of your tailpipe to determine if the part # MF35235 will fit your 2019 Ram 2500. If it measures 2-3/4 inches then yes this will fit and work well. We don't have a way to look up the diameter of your exhaust pipe nor does Magnaflow test fit these on truck models. view full answer...
