    Installed Magnaflow #12586 over the weekend, and WOW !
    Removed the Resonator and Muffler, and had a filler piece made up.
    This paired with the Zabteck T/B, and K&N, has increased my Smiles per Mile by a Ton.
    It is just as quite at idle, but any input of the skinny pedal, and it sounds like it should have from the Factory. Overall i am now at 15.5mpg/city and 20mpg/highway.
    Up about 2-3mpg from the 91performance tune from Torrie.
    #12586 has the Center input and Offset output to make the install a little easier.
    Also because this is the longer 'quieter' muffler, i had to move my hangers a bit to keep it secure.

    Did you get in on the DOB buy ? I am in for the stage 1. Jason is an hour away from me, so all the stuff that doesn't crossover from the mustangs, he'll be able to help with.

    did you go for stainless or aluminized? i modded a gibson exhaust for an explorer for mine and need to move the first exhaust hanger. not sure if i should move it on the frame of exhaust. tack welded the inlet and outlet an put a dime size hole in the inlet. going to have a shop do it right, if moving the hanger is a PITA

    I went with stainless to match the rest of the system.
    Moving the hanger is easy, its alot better than burning a hole in a brand new can.
    Hardest part is getting pipe bent, unless you have access to a scrap pile of mandrel tubing.
