Underbody exhaust

For some reason the underbody exhaust is really calling my name lately (https://gtmotocycles.com/collections/exhaust/products/gt-rx-griso-8v-underbody-ti). If I read it right, I'll have to relocate the O2 sensor, correct?
Anyone have one of these? how do you like it?
@Trout can comment. I haven’t sold many over the years.
I developed the map for it that deletes the stock 02-sensor completely using the flash tool; https://gtmotocycles.com/products/gt-motocycles-5am-7sm-reflash-tool
From there, you can add the fully dynamic PC-V/AutoTune system. That also requires 02-sensors to be put into the headers. I also offer a full system exhaust that has the sensor bungs correctly placed.
Other questions from there, email direct; Todd at GuzziTech.com

Have it & love it!
First: It really lets the bike show off it's beautiful Italian lines while ditching a lot of xtra weight.
Second: The sound is amazing!
At idle it has a very nice rumble & through out the RPM range the sounds gets better.
At steady cruising speed it does not hurt the ears at all.

This past weekend my brother came up for a ride.
I put him on the Griso & I rode the Vic.
I asked him to pass me at some time during the ride because I wanted to hear how the bike sounded.

He passed me when I was running along at 70 & the sound was just awesome.
He pulled in front of me then down shifted & rolled on the throttle.
Music!
 
@Trout how did you end up handling the O2 sensors? Place them yourself or get the full system? I'm not sure where locally I could get them put into the headers, although I'm sure there's somewhere

It was my bike originally. I welded in the sensor bungs into the stock double wall headers. I do offer a full system now.
