Mf Series Cat-Back Exhaust System, Made Of Stainless Steel
Excellent exhaust!!!
This exhaust is the best thing I have done to my truck yet.It is very easy to install, usually the words "bolt on installation"scare me,but not in this case.Everything fit like a glove!! It has a good low rumble to it and you can still hear the radio.I would reccomend this exhaust to ANYONE, plus, since its stainless you'll never have to buy another one!!!!Perfect!!
