Even for reliability reasons that seems like a direct violation of parc ferme principals... and if you're suggesting they are doing it for a performance advantage then how is that allowed?
Direct quote from the 2014 Sporting Regs:
Any work not listed above may only be undertaken with the approval of the FIA technical delegate following a written request from the team concerned. It must be clear that any replacement part a team wishes to fit is similar in mass, inertia and function to the original. Any parts removed will be retained by the FIA...
A list of parts replaced with the specific agreement of the FIA technical delegate whilst cars are being held under parc fermé conditions will be published and distributed to all teams prior to the race.
The argument would be around "similar in function", or more specifically, the definition of "similar". Obviously it speaks to an intent.
I could quite easily argue that any exhaust manifold performs a similar function (and they would not actually look that different, so mass and inertia would also be the "similar")...
