Is MagnaFlow Performance Muffler # MF12254 Loud and Unrestrictive

Question:

dear sirs, i was considering magnaflow 12254 muffler for my truck. stock piping from cat to muffler is 48mm and the endpipe is 45mm. is this muffler going to be loud? and will this allow more free-flow than the stock? regards,

The MagnaFlow Performance Muffler # MF12254 that you referenced is a straight-through style muffler which means that it will be noticeable louder and will be much more free-flowing than the stock exhaust. This is basically a straight pipe wrapped tightly with noise reducing insulation that allows the exhaust to pass through unrestricted. Since this has quite a bit of insulation and length it won't be super loud but it will be noticeable louder.
