For the record, I have the LG headers and love them. Lou and his team were always very helpful, and Lou answered my PMs without hesitation. Good luck getting that type of feedback from the other guys (I tried).

And back then, there were ONLY TPIS headers available. that is why we built our headers in the first place.
Since we were the largest F body Borla dealer in the country for a long time, we worked a deal out with them to build OUR LG headers for US exclusively.
I am sure that you know what the word "exclusively" means, and that is that LG Motorsports owns the "Design" and Borla has agreed to build them for us and only us.
So LG Motorsports owns the design, and of course, not until I give them a Purchase Order, do I own the headers.
That is like GM owning the design of a part that they sub out and the supplier can not sell the part to anyone else because it is "exclusively" owned by GM.
I hope that makes things a little more clear for you.
Some day You will have to tell me in private what LGM did to make you rail against us at every opportunity.
Thanks guys,
Lou Gigliotti LGM

Your headers work well for their designed purpose but so do the other header designs. I'm sure that Dynatech, Kooks and the others spent time and $$ with their designs also. You have an exclusive design made by Borla and sold only by your Company. Dynatech, Kooks and the others are non-exclusive designs sold by many retailers. I like having a choice on price, design, materials and availability. I decided on Dynatech but that doesn't mean my choice is right for anybody else.
The posts on this Forum have a strong influence on my purchases. I appreciate the fact that you personally respond to posts, very few of the other retail owners do so.
Nothing against you or your Company, just my opinions made public on this forum. I wish you the best of luck in your Racing career and in your retail business.

That is why any legitimate coater applys ceramic to both the inside and outside! It will actually extend the life of your header, increase hp, and looks better (if that matters to you). Far different that just wrapping header.
You don't have to coat them. But I constantly had a CEL with my first C6 (non-coated headers). This time I coated the LT's prior to install on the A6, especially since there is no tuning avail, and with 5900 miles have not threw a CEL once.

However, when it comes to performance you may want to rethink the above statement. Ceramic coating will normally boost power when applied to headers for two reasons. First, the coating promotes denser, more potent fuel/air charges by insulating the engine bay from exhaust heat. At the same time, it accelerates the pulsed-vacuum effect on “tuned” headers, resulting in more effective scavenging of cylinders. The increased velocity of exhaust gases produced by higher exit inertia not only clears each cylinder more quickly; it also draws in the next fuel/air charge more efficiently.
As far as bling factor, I chose to coat for looks also because after a few heat cycles the stainless was an ugly yellow like the picture posted previously. Nice to look into engine bay and see shiney silver instead of burnt yellow. Was worth the $195 I paid to the local high performance ceramic coater. He does pistons etc as well

.Man, $195 is a good price! I think coating mild steel headers is good because mild steel is a very good thermal conductor. By my estimate, (and nobody will give out the thermal conductance value of JetHot, but I used aluminum oxide) coating mild steel brings it to about the same as 300 series uncoated. Now you are right, coating the 300 series will make it even better, but I think it might be only slightly better. Sure would be interesting to see a before and after dyno pull with LG's uncoated and then coated.

I've had Jet Hot coated headers in the past, but I'm definitely not a fan. I'm the do-it-yourself type, and I'm always changing something on my car, and the ceramic coating made my old headers a nightmare to keep clean. If you even look at them with grease or oil on your hands, they get a permanent, baked in stain. To each his own, but I much prefer the look and durability of raw stainless. I never noticed any benefit to the coating in my C5, no change in temps that I read about at all, so it's not going on my LGs.

You know the big color advertisement of the Supermaxx system that you always see. Well the first thing listed under the title "Chevrolet Corvette C5 System" is "Long 1 3/4" Tube Design"
You can see this advertisement on the Tbyrne sight right here:
