I recently ordered a Quicksilver exhaust from OutMotoring which is called a downpipe back exhaust as well as some '17x7.5 wheels. I'm assuming that these will kick me out of stock into STX? Can anyone confirm? Thanks in advance!

 

The wheels aren't legal in stock.

Don't know about the exhaust, "Any part of the exhaust system beyond (downstream from) ... the catalytic converter ... may be substituted or removed" (Sec 13.10.E) provided its not too loud.

 

I didn't realize it till I was reviewing the SCCA documentation last night. Thanks for the confirmation.
