The only way the dealer could deny warranty repairs is if they have proof that the issue is caused by the aftermarket parts. Intake and exhaust are warranty friendly mods. Chips/ECU programming would be risky. Your best bet is to check with your service advisor to see how they typically handle things. Every dealership is different.
