I've been running a Borla XR-1 Oval for several years on my H-prod Honda.
Very happy with its performance. It is very quiet, yet makes very good power.
I usually hit around 89-90db for sound.
Fitment is a bit of an issue for me due to lack of ground clearence. I have to use my old IT tires on the rear to load the car on the trailer, but that has more to do with my trailer ramps than anything else.
I have a small turn down just behind the driver. As such, it is makes the car sound much louder inside than outside. I suspect if I had a traditional rear or side exit it would be much quieter inside.
