Earlier this weekend, after installing my Rally Armor UR mudflaps, I was crawling around under the OB spraying some key bolts down with penetrating lube (rear diff, transmission) in prep for some fluid changes I plan to do this week.
While on my back, I spent some time looking at the exhaust. I had been set on the Nameless system (with mufflers) - but after seeing the size of the single pipe - I think the duals are overkill. With no bumper cutouts, there is no aesthetic reason to keep two exits either.
I got to thinking - did some research and found the Borla ProXS to have a reportedly great flow number with low noise. I'm a past Borla user, having used the XR1 Sportsman on my old Durango. Searched YouTube - but no luck finding modern Subarus with the Borla ProXS. Plenty of muscle cars though
Over a cup of joe in the morning, I read this tidbit below as well -
Was wondering if anyone had any pictures of a single exit on the OB?
Based on eyeball measurements and ease of routing, hacking off the Y-split by the rear diff and running it out the driver's side appears to be the cleanest option. Based on space available, I'm thinking the 14" body length muffler, a clean turn-down topped off by a nice polished tip (similar to Nameless's design).

Then again, I wonder if Nameless will sell me just the driver's side. After looking at their picture - it appears their pipe is roughly the same size as the OEM pipe before the Y-split. All a shop would have to do is mate the two pipes.
I've attached a picture of what I'm thinking.
