Illegal exhaust setup for emission tests
I currently have an offroad y pipe on my z28, but in NC they are cracking down on emissions testing for inspections. I was wondering if anyone had tried different setups to get pass the emissions tests and still have a basically functional offroad set up.
My understanding is that as long as u have 02 sims (your computer read that you have no errors) and they can see catylitic converters under your car then you will pass. This brings me to another question ANYONE TRIED GUTTING A CAT AND PUTTING IT ON THEIR CAR AND STILL PASSING INSPECTIONS WITH 02 SIMS?

My car has gutted cats and it passes in GA. I have heard of some people just taking the heat sheild off of a cat and tack welding it in place for a visual inspection, Again I have heard this... sounds like it might work.

What I had done a while back was get the O2 simms and then I gutted the cats and stuck a straight through pipe through the middle of the cat. That way you don't get that echo or whatever because of that open chamber...thing....I passed.

Is there a way to get your car exempt from emissions. I live in chicago IL and have heard that if your car is under a certain mileage a year or if it is a recreational vehicle you do not have to get it tested. how can someone with a 60s-70s built up muscle car take an emissions test ??

Yup .... what they said already.
If your car has to pass a visual inspection and they check for cats, gut a set of stockers and weld a pipe inside. I ran gutted cats and hated the sound of the extra "resonance chambers".
Since I didn't get any real gain at the track, I just stuck my stock cats back on and sold the gutted cats along with my O2 sims.

Thanx.. that helped alot.. since I already have a 3" offroad y pipe.. I think I might jus get some gutted cats and weld them on over top of the y pipe for the look. It would be the same concept as putting a pipe through the cats... tell me what you think?

So who thinks that in IL an LS1 with gutted cats and O2 simms will pass? All rest stock?

In IL they have an OBDII emissions test. They hook up a scanner to your computer and if you are not throwong any codes....you pass! So put LTs and a cam in your car have it tuned and as long as the computer says your good, then your good.

Also, you only have to pass what the requirements were, for THAT YEAR. As in, a car made in 1990, doesn't have to meat guidelines for cars made in 2000.
