Maybe Leeroy could correct me, but I reckon the heat radiating into the footwells with or without insullation would be unbearable. The paint on the chassis would probably blister anywhere near the cat or mufler.
Leeroys done a great job of getting the system through the chassis the way he has and at least it got him through rego. Again Id be curious to hear from Leeroy.

Regards.
