What's your experience with the Ebay 3" DDPs?

Notice the pic? The number on it is the part number from Toyota...

so just call the dealership and order that number? wow. I haven't bought anything from a dealership in so long... it never even crossed my mind to go through Toyota. haha. thanks GrimJack.

They certainly look nice enough. However, they are made with very thin steel, so they dent easily, and the flanges often aren't flat enough to seal, in which case you need to get them milled flat again.

This is it: http://www.amazon.com/Permatex-80697-Copper-Gasket-Sealant/dp/B000HBNUDQ

You spray it onto the sealing surfaces of your exhaust gaskets and let it get tacky, install and enjoy leak-free sealing! (it does have limits, but like I said I was able to re-use my gaskets several times (never retired them, actually) Just gave them away to the guy who bought my downpipe.

I ordered this copper spray from your link and I just received it. So now I am just awaiting my 57 trim from Albert. As for the spray, how exactly should it be used. You say above to spray on the sealing surfaces. I assume that means both sides. Also, how long does it take to become tacky... like an hour? Do you use it for all gaskets or just the downpipe gaskets? The reason I ask is because I also ordered this gasket set from driftmotion for the turbo. They are very tiny but I suppose we can spray those too. http://store.driftmotion.com/static/i-ct26turbogasketset.php

Thanks!
