manifolds. They supposedly crack very quickly. If I remember a TT member bought a set of prototypes from them at great expense and they cracked after a month of just break in driving. I believe the weight of the turbo, heat, bad welding knowledge and design made for a bad manifold.... if I recall. I called Turbo Boss to order their engine mounts and asked a few questions about the manifolds and they didn't seem to have a lot of answers..I may have just been speaking to the wrong guy but I still was leary. I purchased the engine mounts and they seam sturdy... but won't know anything until my engine get dropped into the car next week. Maybe Turbo Boss has turned over a new leaf of quality... maybe it's BS. :)
