[quote=”JeffC” post=1271]BTW, where’s the list showing point ranges per class? Could that be added to ‘About’?[/quote]
Full documentation on the classification system is linked in the “2013 Autocross Season Policies & Procedures” thread

There you can find the point range breakdowns.
To answer your other question, an exhaust mod is not 2 points. Your engine mods are only 1 point total. What you’re seeing is a +2% increase in HP estimate from the exhaust mod.
