Need help with 04 exhaust manifold replacment. Anyone done it with instructions? How can I tell if I have a California emissions manifold???? Thanks for any help

 

open up your drivers door & find the VIN # sticker & read it, it will say either federal or cali. emmissions

 

Thanks, I'll check. Why would I have a California emissions when I live in Virginia? DO you know the differences. can they be swapped out interchangeably since the California one would be more stringent? Thanks again

 

Most cars if not all are CA emissions. Many years ago, there were a bunch of cars that were only Fed mandated. In the early 70's, some drivetrain options were not available for sale in CA. With the exhaust, if you were buy it from the dealer, they would only carry the one that is CA emission for your 2002 Civic. I would only be concern if you need to have your car smog. In California, some smog stations are strict enough to make sure that you have the right components on your car. With my 97 HX Civic, there were two types of cats that would fit my car, only one from the dealer was approved for CA. The aftermarket ones were not.

 

My original sticker says I have CARB Ultra Low Emissions. Do I need to worry about which manifold/converter I find orwill I be OK if I just follow the one for my model of car for that year? Thanks for the help. I know Jeeps, not Hondas

 

aren't exhaust manifolds warrantied longer since it's an emissions component? I'd go ask the dealer if they would replace it free.

 

If your CAT is welded to your exhaust, some aftermarket ones are two seperate pieces. Also, there is a reason why Honda CATs are more beside the usual markup, they last longer and they are more efficient. I have heard many times that aftermarket CATs do not last as long. Ifyou were tosell your Civic in the near future, just use an aftermarket one.

Many years ago when I had a 79 Celica, I had a cracked manifold. Toyota replaced it for free even though I had around 90,000 miles on it and it was 6-7 years old at the time. With my Civic, I had to pay for it because I had way too many miles on it and I don't think Honda would have ate the cost.
