Wow, it'd really screw up your plans if those of us who actually adopt and test new parts made a policy of only sharing our results with others who contribute to the community's body of knowledge, wouldn't it? It wouldn't be too hard to do either, seeing as how we can create private groups on this forum. (I'm just making an observation, btw. Pls don't take this remark as an implied threat or anything like that.)

can I has invite? :excited:

LOL. I will be making my review, dyno charts, etc., public like I normally do. I was just thinking out loud, in a manner of speaking.

ya I know :tup:

He did recommend Ceramic Coating though, even though at $280

I think ceramic coating might be worth it if you are going forced induction, but on a NA car I do not think you will hit any high temps which might cause issues. With long tubes you are getting better flow over all so you might see a slight reduction in temperatures in casual driving and probably <1% change, if any, in spirited driving.

Hmmm I'd love to see before and after data of ceramic coating tests

If Osiris couldn't tune timing, GTM wouldn't be using it for their 370 twin turbo and supercharger kits, and Stillen would not be using it for their supercharger kit. If Osiris was not controlling timing, 100% of these cars would have blown up by now.

I am just curious as to why he would recommend against heat-wrapping the headers. Wouldn't the ceramic coating pretty much do the same thing .. and yet that IS recommended?? Can you expound please?

Right, and I'm confused about this as well. When you take out the stock manifold, the heat shields come off. So you put in aftermarket headers and you don't have heat shields anymore. I asked him if we should wrap them then. His answer was no, because the better flow and design of the LTH's will reduce the temps, thus negating the need for heat shields. Then I read that he's offering ceramic coating, hence my confusion.

I emailed Tony last night, and his response to me was "The temps will be lower but the coating cannot hurt it will only help. The coating just keeps more of the heat in the tubing which is ideal for a force inducted application EPECIALLY turbochargers since they build power off of heat."

At this point, I'm under the impression that if you're planning to stay NA (as I am), it's really not necessary and an unneeded extra expense. But I'm waiting for Tony to confirm on that.

Update: I just spoke with Tony, and he has confirmed that if you're planning to keep your car NA, there is no need to ceramic coat. It will make no difference performance-wise (in an NA car), and the headers aren't near anything heat-sensitive like fuel or oil lines.

And if you plan on going SC later?

You can always take the headers off and have it done at a later date, which is what I will do if I go SC at some point.

ah makes sense

Once again I am thankful for your clarification Semtex.
