It depends on where you are if they check for the cat and other emissions equipment.

That's why many people hollow out their cat and run it like a straight pipe. Though it still looks like a cat is there.

Note that I run MAF (1989), and I had no problems or lost performance from removing my AIR, timeslips to verify. MAP on the other hand (1990 and up IIRC) I've heard it causes issues and lost performance.

Re: Pulling out the SMOG Crap!!
I got code 43 put a resistor on the knock sensor wire then to ground no help. Starting touching everything. Only had it 4 months got to the distributor and found it was loose and retarded along way. Adjusted the timing and tightened the bolt runs great. Do i still need to prodram the ECM? Thanks for the help.

Re: Pulling out the SMOG Crap!!
If your knowledge comes from automotive magazines, than I guess that explains your ignorance.
When you've owned a race shop for as long as I have, worked in dealerships, built dozens of motors, read as much sae documents as you can take, do your own dfi tuning, etc _THEN_ you can tell me i'm wrong.
And btw, my original statement was: "And sometimes the added backpressure of a cat can actually increase the performance of an engine." Which has been proven in the "magazines" as well. I don't think I ever said to use stock manifolds instead of headers, etc. But you decided to go off and list all the things that would absolutely positively be a negative restriction. Fine, if thats how you argue points than whatever.
But since your our new in house automotive expert, I'll back off now. Do you have a column in super chevy?
