Sts - Wrapped Exhaust -- Inside!!!!!

i know things are still a bit up in the air, but it seems that were starting to see more and more results from these setups.
Looks like the premiere test is maybe 01/02 manifolds with ceramic coating, header wrap, ceramic batting, and then sprayed to lock the moisture. (correct in that order?) Talk about heat retention!

I'm not going to bother with header wrap on mine, just the ceramic insulation blankets. I think the ceramic insulation will hold up better over time, especially since it has 2mm alum backing and i'm going to skid plate the Y-Pipe since it's about the only part of my car that can scrape on a speed bump.

I dont know if you guys have seen this, but alot of road racing and very very extreme High HP turbo cars in japan use Ti for intercooler piping.
Ti is suppose to be the best but its not cheap and really hard to weld...
Just a thought

Verdad Gallardo how about this... GENERATION II COPPER HEADER WRAP
Generation II Copper Header Wrap improves heat resistance up to 30% more than current technology, by utilizing a new proprietary coating developed by Thermo-Tec; improved Thermal-Conduction-Technology (T-C-T).
Generation II Copper Exhaust Wrap creates more horsepower and reduces under-hood temperatures, increases exhaust scavenging, withstands continuous heat up to 2000ºF, contains no asbestos.
Generation II Copper Exhaust Wrap is sold in one or two inch wide, 50 foot rolls with a low profile 1/16" thickness.

And this...doesn't seem that it would seal it off so much to cause the pipe damage, yet seal it in enough for pressure increase in the turbo applications...
CLAMP-ON PIPE HEAT SHIELD
The flexible clamp on pipe heat shield blocks over 98% of the damaging radiant heat of the exhaust.The High-tech composite construction of the heat shield provides the ultimate in protection.
The kits come complete with all clamps and install in minutes.
Clamp-on pipe heat shields are available in one, two and three foot lengths. Clamp-on pipe heat shields incorporate Thermo-Tec's proprietary coating technology developed by Thermo-Tec, Thermal Conduction Technology

Yeah so it should go like this white powder coat on the outside+ ceramic coating+ header warp 
Now I just have to find a place to do powerder coating

yes, i have 100 $ in just having the wrap kit sent to me.! its always 100 $ here, 100$ there!!! 
As w/ anything...there is overkill I'm sure...but it is a matter of physics I believe that there is a direct correlation between the amount of heat produced and retained to the amount of pressure built...am I not correct? I believe that I remember this from some training on steam operated tire curing presses several years ago...

They were dyno'ing a STS twin turbo GTO the other day at Thunder Racing. They were running it at 8 psi and eventually got 540 rwhp out of it on a stock LS2. Not too bad, but what was odd was the fact that it gained hp on each successive pull. It did especially well when they didn't kill it between pulls. The rwhp went from 525 up to 540 just by hot-lapping it. Since the air piping and engine were heating up, I have to wonder just how good it would've done if the exhaust was hotter on the first pull.

I experience this while I drive. The harder I drive it, the faster is gets. It's definatley noticable on the old butt dyno.
I've seen this effect at the track too with rear mounts. The wrap would eliminate the need to drive the hell out it to get some decent times/numbers IMO. I think every turbo guy (front or rear mount) here knows that when their car is cold and they accelerate for the first time in the morning it doesn't feel as strong as when all the tubing is warmed up.
