Well I installed my new Magnaflow cat back, 15000 SI/SO on my 11 5.0. It sounds nice when you get on it, but has no tone when idling. I'm thinking that I will need to replace the front pipe which has the resonator on it. Anyone know of a source for this pipe? I will likely visit a local exhaust shop and see what they can make up for me.
Anyone looking to do exhaust on these trucks should look at replacing the resonator too.
Did you install it yourself? I called the muffler shop a couple of days ago to see about having a True Duel Borla set up put on my 5.0L and they told me that they cut the reso pipe off these trucks when to put aftermarket mufflers on them. I suppose all muffler shops do things differently though.
Sounds like the muffler shop you are talking to is building the exhaust system vs installing an off the shelf cat-back system. I do all of my own work and installing this system was super easy. I just would have liked to have had the option to remove the resonator.
Unless you've already done so, the resonator should be replaced with a 3" pipe so the whole system will be 3", as the Y-pipe up to the front joint with the resonator is also 3".
Just so you know, Flowmaster replaces the resonator with a 3" pipe in every system for late Ford trucks, replacing everything from the Y-pipe on back with an all-3" system for better flow.
