After the up/down pipe install, the only heat shield that was left to use was the one that covers the turbo and part of the DP. It did need to be modified to fit, but I would at least keep that one on. There may be a way to keep the others but I didnt.

Some kind of heatshield for your pipes would help greatly extend your CV boots for one thing. I wraped my uppipe, modiflied my turbo heatshield and wrapped my downpipe. Wrapping will most likely decrease the life of the uppipe and downpipe but will overall be good for the engine / performance in the long run...Custom heatshields or high temp coating would be ideal.

If you keep the turbo heatshield supports in place, you can re-install the turbo to downpipe heatshield. Acually, you don't need the supports, but just need to reinstall the bolts than didn't involve the supports ( two little gold "L" shaped brackets under the heat shield. You can reinstall them with the aftermarket downpipe if it is not a bellmouth, or a wastegate seperate pipe, without modifying the heat shield. You just put back three or four bolts IIRC, and this will hold the heat shield on with no problem. I think two of them are down by the uppipe outlet (by the bottom of the turbo, but I can't remember where the other one or two go into.
