Hi,
I went SCCA solo2 auto-x'ing once and I was placed in STX class(in the novice group obviously). At that time I had the factory suspension upgrade (they call it the SPT kit i think?).

I haven't gone for a while and now my car has a Cusco rear sway bar. I wonder if this little mod would throw me into other groups.

Rear sway is not legal to have in stock, so again it would be either STX or ESP.

Here, have a look here for stock, street prepared and ST rules:

STX as long as you don't have ANY mods that affect boost, including blow-off valves (for whatever reason).

 

How about turbo-back and uppipe? what class will I be in if i got put those on my car?

 

High flow catalytic converters are allowed, but must attach within six inches of the original unit. Multiple catalytic converters may be replaced by a single unit, provided the single unit is within six inches of the original primary unit. The resultant configuration must meet Federal emissions standards at normal vehicle operating temperature.

Here's some reading for you... http://www.moutons.org/sccasolo/

As long as somewhere, you have a cat in the exhaust. You cannot run totally catless.
