Baffle-Ectomy: Removing KTM 790 Duke Akrapovic DB Killer

Okay. So here it is... The video you've all been waiting for. One of the scariest things that I've ever done. And I've done a lot!
For the sake of parity I only used GoPros to record the comparison shots just as with the original. There's nothing recorded on my Evistr or on external mics. Conditions were dry, but very windy/blustery so there's a bit of intrusion in the 'baffle out' clips compared to last year's 'baffle in' footage.
It's quite a long video because it's a how too, what not too, and comparison video all lumped in together.
How too starts: 2mins 12 secs
Comparison starts: 18mins 25secs
