Sorry for the holdup guys!

The process was only to cut into chamber 1 and remove half of the insulation and cover only half of the holes.

Living with the sound difference for a few days made me wish i had closed up the whole tube and removed the whole insulation from chamber 1. The positive side is, if you just want to go quietly about, it will only turn heads when you step on it. Considering i travel with my family all the time, the last thing i want is a lousy exhaust, i think i achieved a moderate grumpy sound with a touch of loudness, still without being intrusive at all! (with the music up you still wont hear a thing)






WARNING! the wig stuff is fiberglass composite mix, dont breathe that stuff, dont touch that stuff, dont even look at that stuff, take it out and dispose of it, it WILL become airborne after a while. You have been warned.

And finally, i dont like uploading things to youtube so have the video file instead!
Filmed it from underneath but the sound is identical standing from behind
