MOT emissions Failure with a 200 Cell Sports Cat - Help!!

[Quattroking]

Good question, there's no extra flow restriction, just the cat doesn't work effectively.

You can cause flow restriction overheating a ceramic core cat, basically it melts.

And if you use launch control/flat shift/anti lag it melts any form of cat and blows them out the back in little glowing bits.

Same happens when TDI EGTs get high, even high enough to see bits of VNT/turbine exit the pipe!

harder to do these days, I found one, but they cant put it through as i've just failed... super stuck right now.

This is why my TTRS is still SORN without an MOT, just can't find a friendly one anywhere near Swindon any more and don't wanna try the 200-cell and register a fail! I had looked at getting a GESI-300 or HJS-400 and make up a pipe on v-bands to swap over, aparrently should get me through. But nobody seems interested in doing any custom fab either. If you find somewhere, do let me know, maybe can group-buy like old times. Need a solution for the RS2 as well!

Chris, what was the outcome? Did the new CATs work?
