Speed Daddy's site states 1.5" Primary - 2.5" Outlet , while the Speed Daddy Ebay store states Inlet/ Outlet: 1.50"/ 3.00".

Is that just a typo, or do they make a 3" outlet for a 3" cat-back system? I don't see a 2.5" outlet for sale on ebay, and I only see a 2.5" outlet listed on their own website.
