I Found This Video On Youtube, And Its About A 1998 ES With A Short Ram. My Question Is, Why Doesnt This Have A CEL? Usually The Weapon R Intake Gives Check Engines.

probably, since the first gen. motors weren't as sensitive as the 99+ motors with two throttle bodies and other stuff.

This only happens on 99+ cars.

I've said it before, and i'll say it again. You want noise? Cut a section of the bottom of the airbox out - enjoy. If you can turn a wrench, then you can go as far as running some ducting into the cut airbox

 

How do you know there is a Weapon R intake in this video? I have a 98 ES300 and also had issues with my CEL while using a Weapon R intake. My CEL came on every 150 miles or so after resetting the ECU. For all we know they are having CEL's but not seeing it on this particular video footage. They could of reset it and it hasnt come back on during the shooting of this video.
