The mufflers I have are 2-1/2" offset in and 2-1/2" center out.

The Dynomax official site shows it as center in and out which is incorrect. Every other site shows it as offset in and center out both with 2-1/2" diameter. Part number 17289

Found this just now on the Advance Auto parts site for $195.99

Dynomax Ultra Flo SS Universal Muffler part # 17289




This is one of the box labels on the mufflers I have (dimensions are on the label in inches):
