SCCA Class Question (2016 Rules) - Test Pipes on a NISMO

SwissCheese

I'm planning on doing my first SCCA Autocross event next weekend, but I'm not sure which class my 2012 NISMO fits into. My only mods are FI Test Pipes, FI catback, and K&N drop-in filters. I looked through the rules, and it looks like the NISMO is in class Street A.

I'm trying to figure out which class the test pipes put me into. The rules for the Street Touring class say that "Any catalytic converters are allowed", but I wasn't sure if they considered test pipes to a form of 'catalytic converter'.

So does that put me into the A - Street Touring class, or the A - Street Prepared class?
