Emissions Question
Alright men, I got a letter in the mail sayin my truck needs to go through emissions and pass. I always thought here in Connecticut that diesels did not have to pass, but its only if they are over 10k pounds.
So I have 2 questions,
What does my truck weigh?? Its a reg cab long bed.
Where can I get a cat??? I don't have the stock stuff, I always thought I would never need it, and tossed it

It does not weigh 10k. Somewhere around 7-8k depending on fuel load and whatever stuff you might have with ya (tools, etc.)
I'm not sure if our trucks had kitties. I think my just had a resonator on it when it took the stock system off. Can't remember.

I was thinkin of callin the DMV and sayin my truck with all the tools in the bed weighs over 10k, since my truck does have my business name on the side.
Unfortunatly I tossed all my stock stuff thinkin I would never have emissions. Live and learn I guess.

they typicly go by registration weight, not actual weight. you could try going through without the cat, you have a 50/50 chance that the kid running the place wont know the difference. if asked play dumb and say "it was like that when I bought it years ago, only new diesels have cats" you never know....
reg cab long bed should be about 6800 pounds

I still have my kitty. Been off the truck 2 years now. It has about 70K miles worth of soot in it but it's in good shape w/ no holes. You could punch it out and weld a straight pipe right through it and nobody would ever know. If you need one and can't find one locally, you can have it for $40 + shipping. I am near Albuquerque, NM. Good luck with those emissions!!

He said they do a sniff test so they will know. Here in NY any diesel under 8k don't get the sniff test but they are supposed to look and see if it is there so punching a hole in the cat and running a straight pipe in it will work in NY.

I'd sure like to know what gases a sniff test would sense that a clogged cat would absorb and not pass through. I don't think a sooted up cat does anything, other than restrict exhaust flow.

Would it make sense that the less air going in = less exhaust gasses coming out? If there is less gasses coming out then the chance of passing a sniff test would increase?? If this is the case, then perhaps it would make sense to put the restrictive factory air box back on for the test 
Just throwing out an idea here to try to help you pass without the cat.

If you want to keep the straight pipe you can put in stack breakers and weld your muffler and cat on to a different pipe and then swap in and out for your emissions testing (about a 20 minute swap after you get your initial setup completed).

You need to do some research with the CT authority in charge of emissions testing and find out exactly what they test for and how. I live in WA, and have to go through emissions testing here to get registration renewed. In my area, for diesels they measure tailpipe gas opacity only, no sniff of the gas composition. Our limit is 40%, I scored an 8, it's just another fee basically, I don't see how anyone here could fail with a decent running rig that's stock or with a stock setting on a chip. Find out what you'll be measured by, and then you can make sure your rig complies.
