Who's done them? Which ones did you go with? What size piping did you use? And what kind of system were you already running, like true duals, single in/dual out, single in/out? What kind of muffler?

Im have 102k on my 4.6 and am hoping that a fellow nj member will be able to help me out with getting them done. I have true duals already with a magnaflow muffler and its ok. But im going back to flowmaster 40's and an H pipe. I just wanna know who had them installed and if you like them?

 

I did em, used the ones from Magnaflow, didnt like em, thought they were way too quiet. I Dummped them all together and went whith no cats into a Y pipe with dual Dynomax Bullets, and used Steeda MIL Eliminators so the check engine light wouldnt come on. Crazy loud now, wouldnt go back.


I used these, but again I didnt care for them:

These MILs work perfectly on an F-150 because the 4.6 F-150 and the 4.6 Mustand have the same cat setup on the computer.
