Last night my db killer for the new Atlas silencer arrived. As standard the sound was a bit fruity so I ordered a db killer from he company that supplied the silencer. All I had to do was take the silencer off, drill a small hole on the underside of the exit pipe, fit the db killer and reassemble.
Looks good and sounds better, sounded too hollow before.
In the end I decided each side needed one small bracket welded on, which will then be braced to the passenger footpeg mounting point. I will try to get them welded up tomorrow.
