Yes, they will fit a 1998, they are shown upside-down in the picture. Take off
Corvette exhausts do not command much sales value except the TI. They can also
be picked up at times from some of the tuners like Lingenfelter.

Please note that if you are putting these on an automatic that you may have to
loosen the transmission mount and lift it about 1/2 inch to get the right side
pipe on. No biggie just something that might cut down on the frustration getting
them to fit.
