Denting the downpipe.. So I have an ebay kit, im trying to get the downpipe as far away from the boot on the driver side steering rack. As it sits now my turbo header presses down on the DP and also slides it back. Would it be ok to dent the DP where this header presses down on it, that way I can slide it out another 1/2-3/4"? It wont be a massive dent, maybe 1/4" deep and 2" across

Yes, a modest dent won't make a noticeable difference. Try to mark it accurately then take it out, use the pointy side of a piece of angle iron on the marked area and strike it with a small sledge. Or if you need a round dent use a piece of pipe. It's best to put your main pipe on a bag of cement or sand so you don't squish the whole thing while you are hitting it. Start slow and test fit it as you go until it is right. Make sure you take any movement of the engine when it's revving into account.
Oh, and you could consider trying to ovalize the pipe just in that area - I've had good luck doing that with a huge set of sliphead pliers, just flatten it out a bit in the area needed. Another option.

I think I may need to do a little more denting. It now clears the boot but im still worried about the heat. I think ceramic coating plus wrap should keep it less than 400 degrees, so Im not worried about melting it.

I heard somewhere that wrapping over cermaic coating was a no no...that it hurt the ceramic or something? Maybe someone can clarify if this is true or not?? Did you already send your pipes out to get coated?

could always put some header wrap around the boot. WS6Hummer's build is similar, very close to the boot, he didnt wrap or coat that i know of and hasent had any problems. truck/c6 setup with AC, so his DP is on the driverside.

It is a no no because it traps water and when the heat expands the pipe the wrap on the outside holds heat in and causes it flake off and what not. I havent got them coated yet because im waiting to make sure everything is mocked up and good to go.
