Single mid - more bass throughout the entire rev range. It's definitely a deeper and SMOOTHER sound. I prefer bass to bark so this set up appealed to me more than the Xpipe. I also like how smooth it was all the time as opposed to it being dependent on my driving style. I'd describe this sound as "S55 Post-Puberty" in that it is recognizable as an S55 but just emphasizes the bassy aspects of the inline-6.

Thank you for sharing. Can you post your exact setup with the xpipe/cat delete?
I'd prefer bass, but will i have drone with catless downpipes and AA single?
Seems like the cat delete/xpipe might be the "quiet" option?
