I'll let you in on a trade secret... (put the catalytic converter back on).

I know don't blow me crap - I let another person in on the secret.

 

Putting the cat back on would me secret easi zest.

Depending on the state you are living in, there are different forms of smog check.
I have heard of people passing the Ohio with no cat by running HEET in their fuel or methanol.
Doesn't work in states with NoX/dyno smog test AFAIK..
He also knew how to tune the ECU so it was tricked out.

 

Exactly - I know in Indiana there is only 2 testing locations left. If you go up there they will fail you on visual inspection for no catalytic converter. On top of this there really aren't any "tricks" anymore with EFI vehicles. Your best bet being the old HEET, E85, and advancing a litte... The thing is - every action has a reaction.
