Due to the Corvette having two different styles of exhaust manifolds, there are two different
versions of the catalytic converter pipes. The earlier vintage (1997-2000) cat pipes (FFR# 25370)
use the same pipe on the driver and passenger side. The later versions (2001-2004) has specific
driver (FFR# 25876) and passenger (FFR# 25877) pipes which are marked from the factory. Make
sure your cat pipes are the correct version in relation to the year of your exhaust manifolds. The
easiest way to tell the difference is that the new style catalytic converter pipes prohibit the collar
from sliding up to the cat itself.
Before you install the cat pipes, make sure the Corvette donut gasket is in place at the exit point of the
exhaust manifold. This is a commonly replaced item from a GM dealership, GM# 12555555.
