Default Best sounding exhaust for 3IS?

I want something decently loud.. Not trying to take out anything past catalytic converter though as I don't want any kind of engine light / sensor issues. I have a muffler delete but honestly, I think it's kind of quiet

O2 sensors are before the secondary cats. Remove them and it'll be louder, and going with larger pipes and a proper X-pipe will also contribute.

Having gone through many exhaust set ups. I like the sound of invidia midpipe + muffler delete the most so far. A regular catback sounds nearly stock to me now lol.

This does not involve removing any 02 sensors nor should you get a CEL. For the muffler delete you can either cut off your stock ones and replace it with a pipe or get a remark axleback with has no mufflers. Same result. In my case, I'm using a exhaust cutout so I have an ark axleback but I bypass it via the valve. Not necessary for you though.
