Catback with headers will flow better than muffler swap with headers. I have the borla s type with arh 1-3/4 headers and high flow cats. It’s definitely louder. I can hear it start from in my house but it’s not so loud that my wife complains. My neighbors have never complained. I would do the touring if I bought again though just to keep it a bit quieter at full throttle and first start. Cruising is decent. And no drone that I notice. It’s easy to find it in a parking lot. Lol. It’s barely noticeable at idle when warm. And best part was with my headers it really didn’t get much louder but the tone was noticeably deeper and more aggressive. If you aren’t planning on doing headers I would do just the muffler swap and look into either replacing the factory 2-1 after the cats or replacing the whole y pipe with a new high flow. I have a magnaflow 2-1 y in my garage that I was going to use but bought headers instead
