Message "What will be done to combat cracking/warpage often associated with tubular manifolds in VG's? Just more bracing?"

The idea that tubular manifolds crack is just wrong. 16g thin walled tubular manifolds (despite what material they are created with) will crack. Adding additional "supports" from the flange to the tubes will only make things worse by introducing a larger heat affected zone.

You have to use thick walled pipe & they will last longer than the turbos that they are attached to.

I made equal length manifolds form my twin EFR 6258 Z & the manifolds have no problem.
