        From Wikipedia:

        "Paint made with titanium dioxide does well in severe temperatures, and stands up to marine environments."

        "The two most useful properties of the metal form are corrosion resistance and the highest strength-to-weight ratio of any metal."

        "Due to their high tensile strength to density ratio,high corrosion resistance,fatigue resistance, high crack resistance, and ability to withstand moderately high temperatures without creeping, titanium alloys are used in aircraft, armor plating, naval ships, spacecraft, and missiles. For these applications titanium alloyed with aluminium, vanadium, and other elements is used for a variety of components including critical structural parts, fire walls, landing gear, exhaust ducts (helicopters), and hydraulic systems. In fact, about two thirds of all titanium metal produced is used in aircraft engines and frames."

        "Titanium metal is used in automotive applications, particularly in automobile or motorcycle racing, where weight reduction is critical while maintaining high strength and rigidity."

        My friend I have found that the older the writing, the less crediable it is.

        Imagine if the Kings writer during the middle ages would have written:

        " The king was a harsh man, the king was a cruel" oops, off with his head, LOL

        History is written by the winners and is VERY biased, IMHO.

        The craftsmanship is bar none on these parts. From a complete CNC machined steel mating flange on the down pipe to Laser cut and TIG welded brackets we really did not compromise the quality at all. This might not be enough to justify costs for some, but to get this kind of quality on a car where there is maybe 1.5cm of space between the factory exhaust and the chassis is crucial. Anything else will rub on the chassis and ruin the luxury these types of cars provide. we are talking fractions of a mm in some cases.

        Not to mention the fact that the parts we sell are not much more expensive then our competitors yet our exhaust system actually replaces down pipes.

        Replacing the exhaust does not require you to remove the engine. Just FYI as well. Thanks.

        Look for any US car for example the new generation Camaro, it is a new design but the aftermarket parts for it not expensive, like the exhaust, catback and the headers.
        You paid 100K for your Mercedes so you are willing to pay $5000 for 2 small pieces of pipes.
        Comparisons to domestic tuning prices are quite simply idiotic.

        There you go guys.

        I also would like to point there is no alternative to this design and I doubt if there will be. It took some serious time to get this done...

        I can't seem to get anyone to notice, but I've repeatedly said I believe your product to be of the highest quality, and it's absolutely gorgeous. Unfortunately, no one would ever actually see it on my car.

        Understood, and if downpipes never come down in price, I'll just leave the stock pipes in place. Again, to me (IMHO), it's just not worth $5k for 15-20hp. There are lots of people who will pay any price for gains, I'm just not one of them. And yes, I know that after a certain point the downpipes can become the limiting factor on performance gains. But since I'm not chasing big horsepower, I don't think it will be an issue for me.

        Thanks for chiming in and for the info. BTW, I spoke with one of your guys the other day - he was very professional and a pleasure to talk to.

        So I guess that makes "ME" my tuner.

        BEFORE YOU ALL GO INTO "FLAME MODE," please consider the following:

        Working on my cars is a hobby for me. It's how I relieve the stress of the week, and I get a lot of satisfaction from working with my hands. I'm not competing with anyone and I'm not trying to have the lowest, fastest, most powerful, most expensive, or most beautiful vehicles in the world or this forum. I don't race anywhere or anyone, though I will occasionally do a Hyperdrive or Test 'N Tune for fun and to prove to myself that I have been successful in improving the car; and I don't put my cars on display or in car shows. I've never had trailer- or track-queens; these cars are my daily drivers. As such, I take on upgrades I can complete in an evening, a day, or a weekend, and that won't have significant adverse effects on reliability.

        I do not consider myself to be better than any professional tuner, and I have a great respect for those that can squeeze every ounce of potential from a motor, transmission, chassis, etc. I'm not in competition with any of them. I just don't get any satisfaction from paying someone else to work on my cars. As a result, I know I will never have the fastest, most powerful, or best looking car. I'm good with that.

        I participate in forums such as this so that I can learn from other people's experiences and make better-informed decisions on the work I want to do. Occasionally, I share an experience. Even more rarely, an opinion. But it's just that - an opinion, based on my own interests, priorities, goals, and values. Some people have found my opinions useful or interesting, others not. No biggie either way.

        *Disclaimer - the following is just an opinion.

        The value of these forums is not just in the sharing of experiences, but of different points-of-view and opinions. Otherwise, what's the point? I don't know about anyone else, but it's kind of boring if everyone just sits around agreeing with each other. Personally, I love intelligent disagreement and discourse; even more so when it exposes ideas or options I've never considered.

        Ridiculing, insulting, or discrediting another user's posts discourages participation, and not just from the one that was attacked. Eventually, you drive away all dissenting opinions and are left with just another useless tool.

        Not really. You've told me what it is, how it's made, and what the price is. But why is it worth $5K to you?

        Ok if you don't mind please google "Agency Power Titanium Muffler Exhaust System Porsche 997 Turbo 07-09" and see how much they cost, it is Full Titanium not just paint.

        I think you are misunderstanding. The piece Weistec makes is titanium coated. It's not made from titanium piping like the Agency exhaust you referenced.

        So.... I'm not sure what your point is here. Wouldn't a solid Ti-alloy exhaust be better than stainless coated with Ti-ceramic?

        Sure but we are not talking about exhaust pipes - we're talking about an exhaust manifold. And the one Weistec makes is one solid piece that is CNC'd. Look the photo again and you will see the CNC marks on the flange. Making that entire thing out of a huge block of titanium would make it ridiculously expensive.

        I'll bet you your boat that it is NOT made out of a solid chuck of titanium my friend. If it was the prices would be even out of your range, LOL.

        Again, Weistec is the BEST in the business for the 63 motor, no question about it in MHO. But this is an exhaust manifolf/pipe.

        God sometimes its sooo much fun coming on here and reading some of the things people post. First there is nothing involving titanium at all it just sounds expensive. To say those dp's are have anything to do with titanium would be like saying MB cars painted in iridium silver are made of iridium, its just the name of the color. Here are my 550i DP's coated in "titanium":

        Click here to enlarge

        Cost me $70 for the pair. Matter of fact here is my exhaust manifold from my RB(which is robotically tig welded and has a hell of a lot of engineering in it and cost 2k) also titanium coated
        Click here to enlarge

        I also lol when people hear cnc and they imagine tens of thousands of dollars. For those types of small parts it isnt expensive at all. Here I had a company digitize a part of my 550i intake then design a replacement that would flow the same at the maf sensor and yet better mate to the new intake and they flow tested all of this on solid works and made them out of solid chunks of 6061 aluminum (which is more $$ than steel) for under $500. That was one set for 10 it was $275.

        And JRCart jumps all over this dude without even reading that the guy is talking about this ONE weistec product which is way high imo. Hell the guy even commended them on the reasonably priced turbo upgrade(I agree). In the end if weistec can get 5k for that product then more power to them but that is definitely a supply and demand thing and not an R&D thing.

        You need to re read my post again. I never said it was made out of a solid piece of titanium - to the contrary I said it was not and if it WERE it would be "ridiculously expensive".
        And there is very little that is out of my price range Click here to enlarge
