Removing emmisions?
My truck passed emissions for the last time and i have heard of guys removing emmisions things from there truck once they dont have to go to emmisions anymore. My question is would it be good to remove any emissions systems from my truck or should i just leave it alone. If it is ok then what could i remove and how. The truck is an 88 f250 351w.

You can get a shorter belt at an auto parts store to bypass the smog pump.
Then just disconnect everything else and plug the vacuum lines. Mine had a small (1/2" or so) pipe on the back of the heads that was connected to the exhaust somehow and made a lot of noise until I plugged the holes with bolts.

In the case of the modern diesels there is a lot to gain both in reliability and efficiency by removing emissions equipment. EGR is a bad thing for diesels, how could pumping hot air into the intake to make combustion less efficient be good for an engine? Diesel particulate filter systems haven't been very good either causing all sorts of oil dilution problems and flat out wasting fuel to regenerate the systems. I am not going to say that removing emissions equipment is always good, but there are very good reasons to remove emissions equipment in some cases.

If it sounds like you have an exhaust leak examine the A.I.R. check valve at the back of the intake manifold and the crossover pipe going to the back of each head.
If it is rusted through you can plug the heads with a short 5/8-11 bolt.
EDIT: I see Glen beat me to it. That's what happens when you have too many threads opened in tabs..

It can be done. I don't have any cats, egr, or smog.
The cat was clogged, so I took it off. A.I.R check valve was rotten again, and yes I have replaced it before. So I got rid of the egr and crossover pipe. Then I just went ahead and took off the smog. Didn't figure it was doing any good anyway, since the rest was gone.
Its just two bolts that hold the smog pump off, and it get it completely out of the way.

It is a federal violation subject to a $2500 fine for the first offense, and up to a $10,000 fine... if, you are a dealer or licensed repair shop.
Prison is never mentioned.
And a felony is a crime punishable by a (possible) term of more than 1 year.

i don't understand why anyone would want to reroute burnt exhaust back into your intake, think of all the carbon unburned fuel that is being dumped back into your system, I say take it all off, my runs great without that junk on there, and think of the efficiency that can be gained by not turning the smog pump anymore, remember its a small air compressor. when running its trying to push air into the system (with no filter).
