My Ride: 02M3T
We pressure tested the stock manifold to over 10psi with no failure. I can't say every manifold will do the same, however we have options. We have a CNC'd intake plenum flange already made along with a pile of fab components if the stock plenum decides to give out. I also plan on carbon fiber wrapping stock plenum as another possible option.
