Just in case you were curious, here is a short video of my Thruxton idling with open pipes:
Thruxton Open Pipes Video
I am going to install the Specialty Spares megaphone EMGO system and I thought I would get a head start and pull the stock cans.
The video does not adequately represent the booming loudness of straight pipes though. When I revved it a bit, some of the neighbors stick their head out to see what the racket was all about.
