Hey guys, I haven't been aroumd in a while and saw this thread and wanted to update...
I went about 2 hrs. from my house about 2 months ago to get my cat cut out (it was destroyed inside anyways) and had an 18" Magnaflow installed and Wow!!! This muffler is awesome! No drone at lower end RPM's but sounds evil at W.O.T.
MPG's remained virtually the same... Maybe a tad lower... Nothing to whine too much about, I had the guy weld up dual exits (diagonally out the sides) and had 3" slash cut chrome tips...
I personally would recommend the Magnaflow over the 40 Series, I've heard it on a Taco, with the 3.4 and there really is no comparison...
I paid $350 out the door for everything...
GO MAGNAFLOW!!! :bigok:
