This is the muffler delete kit, with the 4 inch tips. I had it on for a weekend and it was too loud for my wife. It is basically new. This cost me over $400 new.
Just wondering if you looked into this b4 you had them installed. Does ford void any of the warrantys when these are added since there wont be the back pressure or anthing? Not a mechanic, so don't know a whole lot, only thing i know is I seen videos on youtube and this type of exhaust sounds good (i just don't want to void warranties)
