the exhaust air will pass through the midpipe smoothly but will go back to the crushed sections of the oem axle back. i'm not sure if the diameter of the oem axle back is smaller, but if they are causing some restriction on the way out. in theory, this may result more back pressure and maybe more tq?

Don't forget that people will also pay ~2500-3000 for a tint, clear bra and ceramic coat (myself included) and that's also just for aesthetics. So paying 2k for an exhaust system which can improve daily enjoyment of the car is definitely worth it IMO. Now I do go back and forth with thinking about exhausts. I'll probably end up keeping it stock in the end, because it suits my purposes just fine as it is, but I'd be lying if I said I wasn't tempted.

Along the same lines as several other questions...does anyone know if the rr racing exhausts are electronically actuated instead of vacuum? I really want to be able to cold start with the valves closed.
It says electronic valves on their site but the vacuum actuated valves still use an electronically controlled solenoid.

Not my video or car. In comments someone mentions it’s running a Meisterschaft catback.

?? I agree that it is a bit excessive for my liking....and not just referring to the price

They are full electronic. You will have a key fob up front that opens and closes them electronically. You can power the ignition and shut them before starting the car or the other way around.

Also, will you sell just the axle back parts without midpipe?
Edit - I just realized the axle back only configs on the other Lexus v8s fit borla midpipes
