Hey fella's. I got a friends wife calling me wanting help on finding a 4" exhaust for hubby's 05 6.0 for x-mas.Trying to help her find the best deal on a turbo back.I don't know anything on the Fords.I'm assuming you can get a 4" downpipe in one of the kits?Someone please point us in the right direction.Thanks
 
MBRP offers 304ss, 409ss and Aluminized steel in either single or dual tail pipes. Also offered are muffler delete and CAT test pipes for an additional price.

Most kits use a 3.5" downpipe and increase to 4" for the horizontal run. A 4" downpipe requires massaging of the firewall pinch welds (using a whackin' stick or hydraulic spreader) to get the adequate room.
 
I've been on e-bay and wonered why the kits had 3.5" downpipes.That explains that.Thanks
 
I have a 2005 , Installed the Magnflow 4" S/S TB- runs good- no mileage gain if that is what you are looking for. I am happy with it.
