All right 2.5in and out for my 01. In the 98 was 2.25inches in and out right?
So its center / center. Are u sure about this?? Pipes underneath the truck dont like they are centered , the one out of the muffler looks higher than the one that goes in.
Check out the enlarge image of the muffler that borla provides to see what I am talking about
As for the muffler size, I want it as close as it is stock. So 4x9 in -body length 14in- or the 5x11 -body length 22 inches-..... ? Searching for the cat-back exhaust info in the magnaflow page found that is a 5x8x14 inches muffler, so I think that answers my question and the one to choose is the 4x9 oval muffler with a 14inches body lenght, correcto?
By the way, have u heard such a setup in person? (magna muffler on a V6)
