But yes, you can just weld some high flow cats in the midpipes to help with the smell.

Understood - hence the word catalytic
I would imagine the mid-pipes get hot eventually? That's why I'm wondering if a pre-heater of sorts would help get them working well quickly?
How do non-turbo cars have their cats setup? I'd think they'd end up further from the motor in an NA configuration?
