Is it ok to yank out air system ?
Is it ok to yank out air system ? I have an 01 SS (non EGR car), will pulling out the air pump, check valves with air tubes , and putting block off plates on the headers cause any problems even if i get it tuned out
Ditched mine and didn't get it tuned out yet. Still no probs at all. Only the ses light but it's not throwing a code for the air pump just the rear o2's.
BTW there is no performance gain from this just a cleaner looking engine bay. And cures backfiring if the check valve is bad.

Extra work space, less to remove everytime you do work, weight reduction and less systems to have a problem with in the future.
And lets not forget the most important part, it helps make your engine bay look like this, which we will refer to as "The Baller-Bay"!

I would say if you are not running cats, then yes definately get rid of it and get it tuned out. Gets rid of unnecessary clutter under the hood and makes it easier to work on stuff.
If you are running cats, I would leave it in. Anyone care to comment if you plan on leaving the cats in???

Just make damn sure you don't take the car to have a sniffer test done when its dead cold! The cats have to reach a certain "operating temp" if you will, before they start catala-sizing the sheit.
Just like when a plant wants to dump 1000 gallons of **** in a river, and can only dump X amount PER gallon of water, they just put it more water! It's alot cheaper than paying the fine

If you pump in a **** load of air while this is happening, it will appear that there is less pollutants per amount of air coming out, which is true. HOWEVER the same amount of overall "bad stuff" is coming out, AIR pump on or not.

I think the AIR pumps do reduce emissions - they only run for a few minutes when the engine (and cats) are cold. They pump fresh air into the exhaust upstream of the cats. The purpose is to get the cats up to operating temp quickly - any small amount of unburned fuel in the exhaust will burn up before / in the cats with the fresh air dumped into the exhaust. This will heat the cats up quicker - then the air pump turns off.
When the car is cold, it is in open loop and unless your tune is perfect there is a reasonably chance your air/fuel ratio is not perfect.

You are correct......
