i had an ssauto manifold on my car for about 5k HARD miles and never had a problem, no flexpipe on the exhaust and i wasn't using the rear hanger for the downpipe either. i've seen several others without problems with SSA's later stuff.

as for the XSPower turbos, i've never once seen one of those hold up. most blow up shortly after installation. they are thrown together with junk parts bought in bulk.
