how much does it cost to upgrade 2.50" exhaust piping in a 1994 explorer :exp:

Only an exhaust shop can tell you an accurate price. I paid for a Flowmaster 40 Series muffler, with 2" piping, and it was about 140. I called a few days ago, and the guy told me over the phone it'd be about 75 dollars to upgrade to 2.25 inch piping. But it depends where you go, so look around (or drive around, lol) and find out.
