Message yes car was fully warmed up.

yeah thats how i made my first video's but no ones was looking at the info. i will make a new one and post it.

a question about the 02's not being as active, do you thinkit might be because my exhaust is to large for an NA, (stay with me here) ever since i installed the dual 2.5" ID exhaust i've noticed the car is more sluggish at lower rpms and some times even chokes up a lil during acceleration, i think because the exhaust is so large for the motor that the exaust fumes kinda of just wallow there way through the system due to insufficient back pressure ( or lack of the proper amount of scavenging) so im thinking (with the 02's anyways, not the rough idle) that the xhaust fumes are sitting around in the exhaust pipes longer then they normaly would because lack of proper pressure to push/pull them through. so because the exhaust isnt flowing past the 02's as fast as they should, the exhaust moves around slowly that the 02 reading are slower??

just a thought, after doing some research on proper exhaust sizing... which i know mine is .25 too large.
