To do it right. Tig weld it. Find a good aluminum tig welder. Hopefully he will know how to prep the area for welding, and can weld. Once you have it welded. Check inside the tube to make sure there is NO dingle berries hanging. If so, you will have to grind them down/off. The last thing you want is to have a dingle berry breaking loose and running down the tube at full speed into your motor.

The other option is to get a new tube from Stillen.
