Muffler Eliminators
Hello, I'm looking into running muffler eliminators on my 1985 corvette, which has a newer L98 engine. I was wondering if doing so will clobber my poor stock catalytic converter. If that's the case, shoud I just remove the cat and fabricate a piece to take its place? I don't have my car next to me right now :'( but isn't there a sensor in the cat, and do I need to retain that? Obviously this won't smog, but I'd keep the old parts for my Bi-annual. Finally, if I remove the mufflers and the cats, how quickly will I kill my valves? Thanks all!

You can run a cat exhaust and muffler eliminators with no known problems.
The old problem of burning valves with a exhaust so free flowing,isnt a problem with an TPI/efi 02 sensor exhaust.This was very true for carb engines.
IT will compensate for it,afaik,with the efi set up.

Does VERY loud mean anything to you?
Do you get on with your neighbours?
If you take out the cat with elim's it will be loud.
