I agree I also would never bolt anything on that did not make power. I sure as hell would not do it if it lost power. However, I get customers now and again that do not care about the performance factor.

To each his own I guess...

A few teaser pics of the first header built for production...

FYI my car was tuned almost stock (just intakes) by the owner of Uprev and picked up 0 HP/TQ.

On another note those headers look awesome. Is there going to be an option for heat wrapping?

I believe he is offering ceramic coating.

In previous discussions with him, Tony advised me against heat-wrapping these headers. Just an fyi.

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

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.

I sure hope that isn't a quote from Tony since I'm under the impression that LTH can't be used with turbo applications. I'm assuming he meant Supercharger but we all know the saying about assuming.

I actually think that UpRev can tune more than AFR...considering Stillen is using UpRev for the tune of their supercharger, shouldnt that mean they have figured out a way to manage all the other stuff... unless the tune coming with the stillen supercharger is actually only tuning the AFR....

fyi - I'm having my wife's car tuned this week with UpRev (same mods - FI CBE, 18"resonators, HFC's, CF Mufflers, Stillenn GenIII) - the tuner claims he can adjust timing - I will post for comparison to the SpecialtyZ tune that Tony provided. One map will be 100 octane - btw since there is pure race gas in the tank right now.

Would you see any gains from having LTHs in that case? Has anybody else thought about this?

I still don't have a car, just curious/dreaming. I'm that guy - sorry.

I mentioned this in the other FI LTH thread. Most of the 90's and back cars had the cats after the header/down pipe. That may not pass the cold start smog requirments now-a-days but having like a 200 cell cat after the long tubes I would think would cut down the raw fuel smell and get you by a quick visual. I know this would necessitate a revised mid-pipe but keep it mind for later Tony. It might keep cops and Highway Patrol from rolling you not to mention the possible smell at stop lights. Not sure how that would impact the #'s though.

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.

G37Sam · 03-31-2010, 07:04 PM

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

Chris@FsP · 03-31-2010, 09:19 PM

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.
