newby here,i plan on putting a magnaflow 14" on my 1998 xlt s/cab w/4.6l.i would appreciate it if someone could tell me what the correct one would be.i dont know what the inlet and outlet should be(center and offset)and also what size pipe the maggie should be.

thanks for your help

would this be the right one #11236(Muffler Size: 4" x 9" x 14" - Offset Inlet/ Offset Outlet) and the diameter being 2.5"

 

Just get the Center/Center in 2.5" and you'll be fine.

The 14" Muffler is sooo much smaller than stock almost any configuration will work. A shop will need to add a piece of pipe to the 14" to make up for the size of the jumbo OEM exhaust.

 

thanks jjmIII i wasn't sure.i just want to make it easier for the shop.

 

On that model truck i thought the exhaust was 2 1/4
I can't remember what the stock size was for sure but 2 1/4 rings a bell?
