I am looking to put headers on my 85 Z-28 can anyone form ma, tell me if I will have inspetion problems if I do?

 

If they are 50 state street legal you will have NO problems... you have to make sure that the headers have an air hose coming out of the top.... most do... edelbrock, hooker, slp... and if they are 50 state legal... they WILL say it,, you can find some good sets on www.jegs.com,. or on ebay

 

Massachusetts law, chapter 90 states that you cannot modify your exhaust, remove emissions components, make louder than when manufactured, etc from original design

However, the 50-state legal stuff is an interesting issue.

Now let me interpret the law for you. Don't remove your cat!
Don't remove your air pump! As far as your headers are concerned - the inspection station won't fail you if they don't see air tubes. Some cars simply don't have air injection, and they don't know which did and which don't. BUT if you are going to drive thie vehicle on public roadways, you must ensure that your AIR and CAT are proporly working, and that you pass emissions reasonably.

I've studied this on and off. The AIR injection in the manifolds do not do anything for emissions that would pass/fail you. But the cat/air is the biggest thing.

 

Thank you for the reply.

 

ummmm AIR is part of emmissions. It takes hot exhaust gasses and circulates it around the cat. NOW if you do not have a visual inspection, your golden. All you need to do is get your exhaust temps up high enuff to heat up the cat. You dont need AIR to pass emissions.. but if you do get caught removing it, it is a federal offence. Yea... big time. This isnt brought up a lot, but its a goverment mandated thing... not just something GM thought was cool to add. If you fock with it... its a bad thing. But I have been in Mass for id say a good year now and im 100% that the modding your exhaust past stock is total crap. I hear tons of stangs blazing around with off road h pipes, ricres with mufflers the size of trash cans... its all bs. NJ is a little bit more on the smog **** side and i know people who have passed with no egr either. The key is visual inspection.

 

Actually your incorrect. In a 3-way cat, the air helps the catalyst burn the fuel. All v8 thirdgens have 3-way cats.

We tested my car with the pump off, then on. The difference was over 500x witht he pump connected. HC went from like 5.xx to .x18

I hate emissions laws! I wish everyone could drive around with open exhaust. And if not everyone, then I just wish I could dammit!
