Hey guys this is the set up i'm thinking of(basic bolt ons) on a 01 ITR:

AEM CAI
DC JDM 4-1 Header
Carsound high flow cat
Apex N1 muffler
VAFC

The questions is, will this basic setup cause my obd2 sensor to go wacked, like my check engine light to go on?

I have a friend who told me it won't affect the obd2

Thanks for your help guys

 

You'll be fine.
