Pro tip: skip the $200 cat-back and just swap the muffler on a daily driver
I put a full stainless cat-back on my 2016 Civic and the drone on the highway drove me nuts within a week, so I pulled it and went back to stock piping with a $60 chambered muffler welded in at a shop in Akron. Way cheaper, sounds better in the cabin, and my neighbors stopped glaring at 6am, so why does everyone online still push the full kit?
