Im looking for a new exhaust system. Would i still need my catalytic converters if have cat backs?

 

You can get straight pipes but will change your exhaust sound( louder raspier), if you wanted or you could get HFC's (High Flow Cats) HFCs are 400 bucks, Not sure how much OEM cats are, or if you could buy just one.
