how harmful if harmful at all would it be to run my car without an exhaust and just the headers and hi-flo cat. i am asking because i am going to have to sell my exhaust and then save for roughly 2-3 weeks to get a new exhaust. i dont drive it that much during the week. i know it will be obnoxiously loud but will it (lack of backpressure) hurt the car?

 

yeah....im not really planning on doing it for the performance gains. its just that i cant afford a new exhaust system yet. its not a permanent set-up.

 

thanks
