Are you happy with how it sounds? Or wishing you deleted resonators too? I plan to do this soon but I think even with the muffler deleted it sounds muffled. But I dont want to be too loud if I delete resonators too so I think I want to delete them and then replace the muffler with something with lesser resistance to the flow.

My main goals were to increase the sound level while also avoiding any drone. For me the sound is perfect and I am very happy with it. It's not so loud that it drones but it is definitely louder than stock by a lot. I also figured if it ended up being too quiet I could just delete the resonator as well, but I think deleting the resonator in addition to the muffler delete would make it too loud IMO.

So no drone from inside the cabin? Have you driven it long enough (like say a 4h drive) and over a longer timespan (2 wks+ is what I'd think, maybe 6wks in this pandemic) to conclude none is there?

Seen lots of arguing about both sides of this, and didn't find a car with this mod around here...

I think it sounds pretty darn good. More than what I am looking to do with mine, but sounds way better than full delete of resonators and secondary cats. Did you leave all that intact?
Also, any sound clips of drive-by would be good. I notice people rarely do drive-by sound clips but those are most useful. Cars sound different under a load than just revving in place.

I've done a lot of driving since the delete. Still extremely happy with it. I haven't been annoyed by the sound once. It's obviously louder but I wouldn't call it drone, just a nice reserved growl.

Thanks! I did not touch the resonator and cats, the only thing removed is the muffler. I'll try to do a drive-bye clip and upload it.
