I just got my emissions test today (something I've been dreding a while). This summer I put the turbonetics kit on my sc300 and I blocked the EGR. Also I have custom exhaust with only one high flow cat. My car passed easily! It even did better than the previous owners last emissions test (last year) either due to the new cat or the valve job/seals I got done this summer. Just thought I'd let anyone who was in a similar situation know.

I meant to post this here, its been a while

 

The "high flow" cat is probably robbing you of 20rwhp. But, that's awesome that you passed emissions. Great job!
