I thought 4th gen cat-backs would work on ours?
I looked at my buddies '97 Z28 and the routing looks the same as ours.
Though mounting points may be different.
I'm probably wrong.

the only differnce is the bend for the over the axel pipe, my brother has the SLP loudmouth on his 91 z28 and that was the only major problem we saw with the 4th gen exuast puttin on a 3rd gen but it still fit great and doesnt bang or rub on anything.
no it is not the exact same from the cat back, it is the same from the muffler back, the lt1 i pipe is somewhat different from our intermediate pipe.... with some modification it will fit with no problem.... it should be worth buying if its at a good price.... and if anyone has any doubts about what im saying... do a search for my name and the exhaust board... me and a few people finaly figured this out a while ago.
