ebay recirculated DDP - fitment and specs?

the heat sheilds stop the heat from baking everything in the area (like the coolant lines, wiring, ect...)

True, it was not my original intent to delete the heatshields (in fact I have two sets sitting around, one that I had ceramic coated). I got a little lazy with the build and left them off, hoping the coating would do the job. So far, so good - it is actually surprisingly cool underhood.
The heatshields will go back on eventually, but I need to cut the rear mani one for my EGT probe to clear it and my turbo one for the extra 02 sensor.

I've seen a few ceramic coatings advertised as "no heat shields needed after application." I think i've also seen JDub say that regarding his but don't quote me on it. Not that i have any experience in the matter but id love to not have to use them if theres an alternative.
they look fine if they're coated as well, and it's a lot more protection...
I had to replace my engine wiring harness because of this, so running all the sheilds is worth it IMHO...

ok im building my own DDP, and can anyone give me the diameter of the wastegate exaust tubing(The smaller size tubing) im going to start a thread on it after im done with pictures. anyone with any type of ddp i just want an average size. thanks guys.

I actually have Heat Shields that were ceramic coated by jdub. Every heat shield on the hot side to be exact
.
Ceramic coating is good, but if you have provision for heat shields...I'd use them. Anything to keep the heat down in the engine bay is a plus. On my next downpipe, I'm going to ceramic coat it and then wrap it.
If you don't have attachments for heat shields, I would most definitely ceramic coat the exhaust parts...don't go cheap...use a 2000 deg rated coating at minimum.

Yeah...it's over kill...I wouldn't call it major though
The ceramic and wrap work the same way...keeps the heat inside the pipe. Ceramic is very good, but you will still get radiated head from ceramic coated parts...cuts it down 50-70% (depending on how hot), but does not eliminate it. BTW, black is the most effective in minimizing radiate heat.
Anytime you use a wrap, the pipe needs to be coated...not necessarily ceramic, but something that will keep moisture separated from the pipe surface. Especially if the pipe is made from mild steel. Same thing for the turbine housing...ceramic coat and a turbo blanket. Both of the above will keep your engine bay as cool as possible.
On another note, I've coated a couple of these eBay DDP's...from what I can see, the quality is pretty good. Good welds...can't say anything about fitment though.

Absolutely love mine... Boosting over 8PSI (stock gauge) with just the DDP, Random Tech 3" cat on stock cat-back and A'PEXi Power Intake with no boost controller in this cooler weather!
i love the way my open ddp sounds vs my friends recirculation ddp its all what you want though but i like my open one more
