I also have the TS cat deletes and TS mufflers, for almost 2 years.
I have my smog test in the Fall this year, but others have done it and passed just fine.

A good tip is to get the engine nice and hot before the smog as the extra emissions when cold it the reason they put 2nd cats on California cars in the first place.

I posted the actual before cat delete smog test numbers way back in a thread and will update with the results from the test with the 2nd cat delete installed.

Its nice to be able to quantify the results.
