welding header collectors

[parsonsj]

Folks often advocate welding on such collectors, but it seems physically impossible to me to get a 360 degree weld around the perimeter of every header tube/collector tube junction.

Burns seems to think that if the slip junction is built to very close tolerances (like theirs), it will be leak proof. Maybe others with direct experience can chime in ...

I'm using Stainless Works merge collectors. They are a tight fit, and I've done nothing to seal them. I don't notice any leaks (the ticking you mention is something I listen for). I continue to monitor this with visual inspections since my O2 sensor is within 24" of the joint.
