With it being so close to turbos does it make more susceptible for the TP or HFC to burn up quicker?
I have never had an issue with melting (metal) cats even running right after the turbo - have always had a properly tuned car. In boost, the AFR drops, but how long can you stay in it? I'm sure the cats get hot with AFRs in the low 11s, but most of the time, you'd be cruising at 14.7 just like any other car.

HFC melting isn't my concern, i want more info on delta 40whp you said in previous post...
I want to know if you loss 40whp only at lower rpm because turbos take more time to spool or if you loose it everywhere on power band? And i want to know if your setup are the same before and after hfc moving?
Dyno sheet?

replied to your PM. You lose power everywhere with cats. My setups did change quite a bit when I moved my cats further back, but has been true dual 3" exhausts the entire time.
