Its a shame that you live so far away. I,m inviting anybody to come and check it himself. I already told you the differences before after removing ONE..!! ONLY ONE catcon bed.....!!!! as i mentioned before, Civic 8th gen has a 2bed catcon. here is some info i,m posting
"Acheiving lower emission levels (ULEV and ZLEV being the target) is the other target Honda has for their new range of engines and to deliver a new level of (low) emissions, Honda has employed the following with the R18A :
# 2-bed catalytic converter located immediately after the mainfold"
copied from site R18A motor - Civic 7-9 generacija - Honda Club Forum
How will the feedback be dead after removing the lower bed of catcon while the upper bed is present and both of the o2 sensors are untouched ?
I am very much aware of the TOTKAS used worldwide. Most common of them being soaked in acetone and thinner. They remove only a fraction of particles and never ever fully clean it.
Your theoretical points are correct on their place and i acknowledge that. Happy ? but i,m not lying either. The car does not drink petrol like sharbat...!!!!
