I remember in the early days of CATS leaded gas was still available next to the unleaded. A lot of people would save the extra 2 or 3 cents more that unleaded cost and put leaded gas in their CAT vehicles. It wasn't long before those loose platinum coated beads turned into a solid brick clogging the exhaust.
 
Rock, I'm not sure what you're getting at with, "The print says. . .," but your link is defines what I grew up understanding what zoomies are. If your local cruise night is the Holly Reunion fwiw I'm impressed. Pretty short cruise though isn't it?

Is NY a state that requires inspections and the window sticker from passing the inspection? If so, your requirements are written for you. You may have to put mufflers on to be legal.

yes and no only needs to pass safety because of age. Yet legal garage can not put on cats not Cal certified and I can not weld that good. Would have to find someone in Pa.

does your emission tag state California Emissions?
 
 
 
only years specified (skip 1995 for some reason) and cars equipped with CA emissions
 
i'd go talk to someone else before you get into a twister next inspection
 
==========================
 
so what is your set-up? you use the plural 'cats' as in multiple so i'll assume 2, just down pipes off cast iron manifolds to factory cats ... anything after the cats?
 
and more importantly, what caused them to fail? is the engine using oil recently?
 
what year is it, what carb/injector/throttle body set-up?
 
any recent changes on the top end fuel delivery?

Yes 15 yrs ago they just came off of cats to duels with what they called an h pipe. Sound was nice so did no mufflers. NY now requires cal cats. When I tried to order ones from on line state not adv in NY or cal? These are org.to car.Will probably just go with mufflers depending on cost.

For 1979, no requirement for Cali Cats, that's only for years NYS required Cali emissions.
Cats are not checked in most of NY, safety only, no emissions inspection for pre-1984.
Shops can't pull off WORKING cats, but under no obligation to replace a defective cat.
So, for instance, your entire exhaust were to fall (off for some strange, inexplicable reason).
You don't need to replace the cats, and it doesn't need to meet Commiefornia emissions, or any emissions really.

Is this an updated version of "Get off my lawn," "Grumpy old man," or both?
It MAY be in the tradition of "Get off my lawn" and being a grumpy old man, but who could resist seeing politicians getting kicked in the family jewels on national T.V.? By a professional kicker?

If your cats were to fall off and something, say a steel bar, found its' way inside them and knocked all the guts out would that be your fault.? Pretty sure not...   Ermm

Say the Y pipe or H pipe came loose and drug-crazed vandals were to poke a bar thru the catalyst and crumble it, knock out all the guts and stole them....

Can't argue with that. First impression was something a little more personal though.

It's been a long time since this was a topic. At some point they learned it was quicker and quieter to just take the whole car.

Mufflers should be less then CATS or even a CAT.

No doubt but that same discount import company probably has $25 mufflers to go with their $70 dollar CAT. Nothing wrong with either.
