X 1459 X.2691 Re - Exhaust Trunk Pipes. We do not understand why you have used copper rivets on the exhaust pipes. We suggest steel rivets, but cannot help thinking spot welding would be suitable, either with acetelene through a hole in the flange, or electric. The pressed pipe appears to be very nice.
