Finally, i got these babies installed on my 3.0. ( since there is only about 6 inches remaining on the inlet pipes-[previously cut], they need to be welded)
First, I went to 2 different muffler shops close to me
1. First shop=They said i have to leave the X for a day or two---yeah right
2. Second shop=They saw the mufflers and have a different shape so they said its impossible--

morons!
And I remember ekaz ( Thanks, Eric!) mentioning Dino's at harlem/addison in Chicago ( about 15 mins from me) I went there, NO nonsense and it took only 45 mins to finish the job. This guy ( Dino)'s welding skill is like holding a pen and signing his name.
Very nice clean work
