Alot of members here have 2nd cats removed and not an issue as they are not monitored..mufflers, not an issue..Does it have an aftermarket radio? depending on how old it is, an interface can be added to allow for steering wheel controls, need model and brand to determine. I'm not familiar with the seat motors so another member will need to respond. got any pics of car yet?
