Install and test Delkevic 8 inch exhaust on Honda NT700V Motorcycle. Loud pipes!

The Stock Honda exhaust sounds like a sewing machine. I ordered and received a new Exhaust, and I go through the process of unboxing and installing it on my NT700V (Deauville).
After install, I do a decibel test, compared to the Leo Vince Corsa on my PCX (guess which is louder). I also do a before and after comparison accelerating up the same stretch of road.
Just a note, someone previously had taken the exhaust off and boogered up the access port for the rear exhaust hanger bolt. Very annoying, but not worth replacing the part.
