For NY the inspection stations are supposed to look to see if the emission devices are present , there is no way to test for emission function other then visually. It has been my experience with my 1980 that I have gotten a safety only  inspection which what is done with older cars just like back in the day. 

So if your car is like mine with no AIR pump you would naturally fail as that visual can be done as well as looking for catalytic converters and because of this I simply will not run the converters and it has not caused an issue at all. 

So if you want to go custom I would forego the expense of  catalytic converters

Thanks guys, great advise. 
 
Sarge, good thing you mentioned Mufflerman.  I couldn't remember their name and I knew I had heard of good things about them from others in the area cruise nights.  I'll have to give them a call.

The shop that I would take my Vette to do the work(mufflerman) will only do the exhaust with cats.  I don't want to spend $250 on a set of cats that I don't need.  So...looks like I'll be looking for a bolt on kit since I don't weld.  Still looking at the Corvette central dual exhaust with headers and magnaflo mufflers.  If you have any thougts let me know.

 
Thanks,
Dave

Guv-ment/EPA regulations have made it next to impossible for muffler shops to do much anymore. ANY modification to the exhaust that would effect tailpipe emissions,even if it improves them, is frowned upon. Shops could, at the very least loose their operating license, and possibly face time in the cross-bar hotel.....

I installed the full dual exhaust kit from.Corvette Central for the '78 I used to own. It went on without any issues and performance increased...at least by my seat of the pants dyno.

David,
 Mufflerman got busted a few years back for not putting catalytic converters on older "hotrods" that originally came from the factory with them. The fine was pretty stiff from what I heard. If you don't mind me asking, what was the price quote they gave you? It had to be over $1k.

 Ian local to you also I just but new exhaust on my 79 L82. Found a "test pipe" on ebay to eliminate the converter. Bought a new rear Y from Wilcox and Magnaflow mufflers
from Corvette Central. It is fairly quiet at idle but has a good roar under heavy throttle.
It feels stronger with this new set up.

Ok, I've made a decision.  I'm going with the Corvette Central duals with Magnaflo mufflers...probably.
 
Sarge, they quoted me $1k, that did not include headers as I have a set on there that won't fit anything but a custom bent exhaust(and they're butt ugly).  That was a ball park over the phone estimate.  It was diffacult to get any type of figure until we started talking a little and he realized: 1.I wasn't going to hold him to the quote 2. wasn't a schmutz who knows nothing about cars and what could go wrong after the job gets started.  Here's where it got pretty cool talking with him.  He said they'd mock up the complete exhaust, have me come back and try out different sets of mufflers to see which I like the sound of more.  That alone should be worth a couple hundred bucks. 
 
I've also spoken to the mechanic who works on my parents car and does the jobs on my truck that give me the willies.  When asked about a hypothetical situation, a 1981 Corvette without cats he just gave me a blank stare and said "there's no computer to plug in".  Then I mentioned the lack of anti-smog equipment for the visual inspection he just gave me a blank stare and said "there's no computer to plug in".
 
When all is said and done I'll go with the CC system.  It'll end up costing me a few hundred less so I can spend more money on other parts.

Just an update.  I did order the dual exhaust with headers from Corvette central.  Took 3 weeks to get here as they were waiting for the a/c bracket which is back ordered.  I asked them to just send it without the bracket.  The woman I spoke to warned me, very nicely, thatI would be charged for the while kit even tho I wasn't getting the bracket.  That was just fine with me since they had already charged me 3 weeks agoLOL
 
My mechanics aide, 16 yr old daughter, and I took the old old exhaust off without issue.  Loosely fit the headers and "h" pipe.  Then decided it was to warm  to work, especially with my back.  Sure it'll take us lot's longer but it's always been about working on it with my daughter. 
 
After this we get to install the new ignition switch, horn button and switch, check for the vacuum leak because the idiot who put the engine in didn't hook up the vacumm line correctly, put in the new door weatherstrip, any tips there would be appreciated, hook up the electronic vacuum advance on the carb etc etc

Finally got the exhaust installed.  A, normally, 3 or 4 hr job only took me 3 weeks or so due to my bad back.  With LOTS of help from my 16 yr old daughter the install was very smooth.
 
For those looking to get this exhaust I would advise you to get it.  Very easy install.  I had to drill a couple holes in the frame for the new hanger placement but that was a breeze. 
 
I can't give you any info on what it sounds like because I have to put in the new plugs and plug wires and the back can't handle it right now.  Oh and I still need to get the igniton switch installed.
 
Ever so slowly getting closer to the road...
