Getting ready to put a ''dumped" exhaust system on my 2007 5.4, FX4.

Im looking at going with a Magnaflow muffler.

I Want an aggressive tone like a super 44, but with the Magnaflow name/performance.

What part number am I looking for.

SI/SO ?

Thanks.

 

If you want a SI/SO aggressive like Magnaflow, the 11" body ( 11366 ) would probably be the best way to go. I'm running two of them.
