Go Vibratechnics. It's the best between stock and the poly mounts.

I have the FR front mount now, this manifold is gone and I don't have any pics of the exhaust but I did have a issue with cracking at the turbo flange with the DP.

Ah ok, I thought you had one like my old LoveFab. I haven't installed mine yet but I will have the DP tied to motor somewhere and then a flex pipe just after for the rest of the exhaust. I don't think we will need to worry with cracking on this setup. The front mounts with the DP over the manifold seem to have more vibration issues and cracked DPs from what I gather.

so can I brace the middle of the downpipe to the engine then get a piece of flex pipe at the end of my downpipe ?

At either the middle of the engine or most likely at the transmission bellhousing to engine flange.

I'm terrible with forums and forgot to check this before I ordered new mounts. Saw that the poly mounts would melt with the exhaust so close, so I wanted to stick with OE style and ordered Megan mounts before checking back here. Oh well. I decided to just dump it out the hood and get rid of the problem all together lol.
