Super lightweight header
It's for an Acura RSX, but damn 7 1/2 lbs for a long tube header!
Using these numbers here the lightest current header/cats/x-pipe system weighs 45.4 lbs for a QTP system.
For these system, multiply by 2 for a V8, add 12 lbs for a Random Tech x-pipe, and another 12 lbs for the cats, and 2.5 lbs for clamps and it's a grand total of 41.5 lbs for a complete system. Dayam!

Not at all. This was built to be a lightweight system. For the racers, it would be awesome if even lighter headers were created. Weight could still be dropped from the x-pipe if constructed the same way, and an open pipe could be used in place of the cats. At one time Halltech made a Ti header system, but I never heard anything after seeing pictures of their prototype.
I like this because I like anything that gets weight out of the car without a loss of performance.

All of the H.P. bike stuff is Ti, and has been for a few years now.. Even comes stock on the majority of them; put a dent in the aftermarket industry..
With the "Corvette Tax", they would probably be 5 grand..

There were lots of concerns about whether the Ti exhaust could take the heat. At least on a bike, even a full fairing sport bike, gets a lot of airflow to cool it down. Anyway, from what I remember the Halltech headers were the shortest lt headers I've seen yet. If a no BS company like LGM sold them in the same style as their current headers, I'd get them....I might have to sell a kidney on ebay....there's another kidney in there anyway....right?

and the bike pipes still turn all different colors of the rainbow i dont think they would last under the hood
if it were 14 pounds lighter it would not justify the higher price they would charge for them

I remember a fellow biker from a few years ago that had to keep repainting the pipes on his naked bike with progressively higher heat resistant paints because it'd keep burning off on him!
Weight isn't the only reason to go Ti. Ti would make the benefits from coatings almost negligible, wouldn't ever corrode, and would be a little quieter as well. Of course none of that matters if the thing self-destructs. The things I don't get is that if heat is a problem with Ti, how can intake valves on racing motors and the LS7 can be Ti and still survive. Two different Ti alloys I'm sure, but I don't know which alloys are used for either application.

Russia has a ton of this stuff.. I say "bring it on!"
True, but it's very expensive to produce and fabricate and it requires special welding techniques. Look at the cost of a stainless cat back system compared to a Ti. The Ti is twice as much, consequently a long tube set of headers would probably be in the $2K+ range.
