Cats coming apart

[Rookie Vette owner]

One of the catalytic converters on my 97 is rattling and I'm looking for replacement solutions. Will the H-pipe off of a 03 Z06 be a direct replacement or would I need the exhaust manifolds from the Z06 also? Are the O2 sensors in the same place? I know that there is a difference between the 97-00 and the 01-04, just not sure to what extent they change.

HI there,
You would need the manifolds as well.
Outlet location is the key here.
o2 sensor locations are close to being the same, so thats not an issue.
Allthebest, c4c5

Is that the sound I hear when I'm backing out of my driveway? It sounds like a bunch of small ball bearings in a coffee can. If the cat's are coming apart is there any chance of damage or blockage of the exhaust? - Ron

HI there,
NO, that is a normal driveline sound.

Thanks for the info about the need for the manifolds.

The rattling sound I have is more related to applying lite throttle while at 35-45 mph. If you let off, it goes away, but returns as soon as you hit the pedal. I thought it was a loose heat shield at first but the mechanic at the dealer said it was the cat.

HI there,
YOu can obtain OEM replacement converters that are just as good as GM for a bit less money.
Simply type "OEM catalytic converter" into any search engine.
