Only the bottom pic is a ramhorn that we are talking about. For the price of the 2.5", I'd just replace 'em. The 2" will work too, but if what's in the pic is what you have, they are mismatched. So if you need to buy a new ramhorn to replace the top one, then might as well buy 2 of 'em and get the 2.5" version. You'll be good to go and never have to worry about them again.

Note about Dorman -- they do make the 2.5" Corvette version but it will have the generator bracket. You will have to cut/grind this off if you don't like or want it. Can't beat the price... about $100-$120 for the pair. For that price, it's worth spending an hour with a sawzall and angle grinder.
