Test pipes are not legal for STS, or any street tire class. I am not sure if you would be in SM or SP.If you plan on running STS, and want to get a LSD, you can only run a vlsd, no helical are allowed. STX is where you would go with a HLSD.
Important upgrades in order.1. Seat time2. Seat time3. Seat time4. Tires, good alignment5. more seat time.6. everything else and more seat time.
learn the car in stock trim before going wild on it. the more parts you throw at it, the more adjustable stuff you put on it will just make it harder to learn the car and get it dialed in. start simple and build up from there. A good driver can drive any car fast, regardless of how much HP, what suspension, how good of tires it has. Stock, low HP cars, will separate the pretenders from the contenders.
Evo schools are great,
http://autocross.com/evolution/modules/news/I have done a phase I and am going to do a phase II this year. I have learned a lot. At your first autocross, see if you can get a vet to ride with, see if you can ride with some one before hand. ask lots of question and LISTEN, at least to the fast guys. Watch what line they run. where they are slowing down, where they are pushing.
