Unhappy 360 (At idle)
Temperatures in the morning was below freezing when i filmed this, smoke out the exhaust pipes as well, normal at this temperature I would say.
The ugly noise in the video is from a metal tube that goes from the exhaust manifold, connected to the air filter box with a rubber hose when it´s in place, som sort of remains of the pollution stuff I think.
When everything is in place I would say the there are no exceptional sounds from the engine anymore, but with this tube open, I must wear earbuds...
Keep em coming... :-)
