can I re-use the gasket form turbo to downpipe???

 

yes if it looks good I have seen it done several times the copper gaskets can be made soft again if you wish , the one you ask about will work if it is in good shape, do not use sealer as it will burn off, torque evenly.

 

Yeah, sometimes you can. You will be able to tell just from comman sence by looking at them. If they still look to be in decent condition to you, then they are probably still good to use. However, at a few bucks for a new gasket, it's good to make sure
