1992 305 TPI single cat?
I have a 92 Z28 with the 305. I am trying to find an exhaust system for it, but all I can find for the 92 says dual cats. I have looked twice and I only see one cat on mine. Should it have 2? Or does anyone know of a cat back system for a single cat? I prefer flowmaster but if anyone has other suggestions please let me know.

From what I understand, the '91-'92 TPI single cat was the weany 2-1/4" setup.
Get rid of it all. Go for the '86-'90 TPI single cat setup. Much better flow capacity.

i ordered the hooker cat back for an 85-89? TPI all i had to do was cut off the flange and round the pipe back out because it comes oval to bolt up to the 4 bolt cat.
