I'm afraid of any answers to this question...lol
what will it take to pass an emissions test with a truck that has straight pipes and the catalytic converters removed.
Specifically, the process and $$. This 1990 Chevy C1500 was bought several years ago, but had to go through it's first emissions test this week and this was found out. Thanks in advance...

This answer should be pretty obvious. The Cat has to be replaced which should cost you a couple hundred dollars at an exhaust shop.

thanks. I was hoping for a little more specifics, if possible. I went to a couple muffler shops today. One said they'd do a "three step" converter that would be under $200. Another said they'd do a dual in, dual out set up for around $350-$400. Just wanted to make sure I had the best set up possible to pass the emissions test. If any body has any experience or thoughts on one set up over another, I'd appreciate it. Thanks.

There is nothing to be specific about. It's a very basic, universal converter for OBD1. I don't know what they are trying to sell you with the dual in and out unless they are building a whole custom system.

Well, the converters are important, but so is the environment the converters have to operate in. If your burning oil or coolant or have engine problems causing the wrong ratio of fuel/air, converter(s) and the inspection station aren't going to be too happy.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Do as you wish about duals but you should only have ONE converter, ONE muffler then just dual pipes so IMO just a waste of metal for that as seen.......
Converter not shown in that,

This system is nothing special or unusual. It's just a basic, universal cat.

My look up showed this as a bargain compared to most. Dual tailpipes may not have been an OE option. They were one some but just 2" vs one 2.5" so same CFM for back pressure and no advantage. Been a long time since real duals did anything useful,

Here is the layout for the 5.7. It shows dual tailpipes out of the muffler but the cat is still one in, one out.

Looks identical to an '83 Suburban I always took care of. Screw the duals after OEs rusted out - FAST - (18 mo +/-) could do just cat back in no time for cheap. Cat forward lasted life of that vehicle, - T
