My assumption is the OP's car doesn't retain the original factory emissions equipment or throws a CEL since most new guys aren't aware of the craptastic STX exhaust rules. So OP, all the orginal sensors in place? Any CEL's(hidden or not)?

STX doens't require OEM cats, just that it doesn't throw a code, or have the code subverted/shut off through the ECU programming.

Which it probably does because that's the common way to do it.

Wouldn't it be great if the SCCA had a "category that provides a natural competition outlet for auto enthusiasts using affordable sports sedans equipped with common suspension, engine, and appearance modifications which are fully legal and compatible with street use anywhere in the country."

Oh wait....

Right, as well as having all the sensors present and functional. No resistor in the UP sensor, etc. With all the Russian roulette that's been played with various DP's and cat configs, it's highly likely that a person unfamiliar with the SCCA rules may have a configuration that isn't legal. Again, just speculation until the OP confirms his setup.

So you aren't allowed to turn off a cel in stx but you are allowed to adjust timing and fueling?

That is correct. CELs are emissions related and "it's all about emissions".

I don't see any engine management mods on his list (why you wouldn't with his mods I don't know). So I doubt he is covering any CEL's, but I guess the question still stands as to whether he is showing one. The catted downpipe should take care of his cat compliance to the stx rules.
See Rule 14.10 (e).
scca.com has a free Adobe download of the 2009 Solo rules.
If he isn't running any EM mods then there is no reason he can't run in stx (providing his mod list is complete).

Depends on if you did anything to the bumper beam to fit the FMIC.

If you cut the bumper then SM. If you've removed it entirely then FP.

I thought all cats were required in ST*?

I play in ESP so I don't always pay attention to the class below me.
