I have a 1975 450SL. Apparently everyone but me knew that this was a bad model year to buy because the mercedes engineers put the catalytic converter in a very bad place.

Anyway, I have now spent $$$$$ replacing all the hoses and wires that my converter burned up . Is there any way to keep this from happening again? Under Nevada law, I can legally take the darn thing off as long as it will still pass tailpipe emission test (no visual for tampering on pre-1980 vehicles).

Any suggestions? thanks for your help.

I'd gut it, see if you pass emissions, if not, install a high flow unit further down stream..

Good Luck!

Thanks for taking the time to answer. Would you take it to a muffler shop or a mercedes specialist?

Not a problem. Neither inititally, as no shop will take on the liability of guting your cat. That is something you'll have to do yourself. As far as installing a high flow cat, I would do some research in your area and see who runs the most reputable/high end exhaust shop. You don't want someone going in there and making a mess of things w/ poor welds etc, etc.

Best of luck!
