I really dont think it’s reasonable to pay such amounts for just tips. If it was an axleback section, or had a muffler on it or something. Just because it’s something for an expensive car, doesnt mean it HAS TO be jsut as expensive. a turn signal light bulb doesnt cost 12 dollars(example off my friends mercedes). it’s a 3 dollar bulb with a 400% markup cuz it fits MBZ. :crazy ---

Your logic is horrible My logic is perfectly fine. My car has 2 tips factory, so thats at least ~250 clams. I wanted to go quad tip, hence the 5 bill price tag for said 4 tips. Ask me a few clarifying questions first if you’re unsure, and THEN if i dont make sense tell me i have bad math or bad logic. ---

They want to make as much profit as possible per unit because theyre not selling many. Then that begs the argument of lowering the price per unit to make the profit larger due to volume sales. This thread isnt about this though. I wanted to go with the quad tip look on my car. I thought that having some blued titanium tips would look pretty nice and classy. I didnt want to go with the typical chrome tips like every single Audi out there. I’ve got 95% factory look on my current tips now, with the exception of them being slightly larger in diameter and being black. It looks nice and simple and clean. Most people dont notice them because of how much they blend in with the car and how minimal it all looks. I really like the quad tip look, something akin to the M5 look. I dont normally see an Audi A6 with quad tips. Pretty much every single one was the regular one tip per side, and I’ve only spotted one in Albany with two tips on one side(factory too). I plan to go quad tip with mine. It’s really nothing but a slight visual change, to kind of keep things fresh. ---

Heaps of info on anodizing titanium online. Adam, this may sound like a completely moronic question, but I have to ask because I simply dont know. Can a tube bender/expander machine be used to make a somewhat of a rolled tip? The flex joints on my car’s exhaust are not flex pipe, they are ball and socket type. Would it be possible to use the piece of titanium pipe in the same machine to kinda push the edges of the pipe inward and round them off same as you would making the ball and socket type flex joint? Does titanium work require it to be under certain conditions? Such as heating it prior, or cooling it prior, or using some kind of special lubricant? Is it more or less malliable than say steel you use on exhaust piping and is more likely to deform/fold/crack/tear? ---

Heaps of info on anodizing titanium online. Yeah I read about it on TI, and I have done some before on RC car parts with a DC power supply and the chemicals. My little knowledge of titanium tells me that it is brittle and wants to snap back into shape, so how does it actual roll and hold? Does it need allot of heat to make it malleable? > [@y0](https://forums.speedlife.net/t/y0/26279/6): > > Adam, this may sound like a completely moronic question, but I have to ask because I simply dont know. Can a tube bender/expander mac…than say steel you use on exhaust piping and is more likely to deform/fold/crack/tear? Like we talked about the idea of a simple press with machined dies to form it I think wouldnt work out as well as a roller lath setup. I think it would be asking too much of the metal to move and change shape too much and it would either split or deform. ---

Die forming titanium tube requires close tolerance dies and forms and some serious tonnage. While being somewhat elastic for lack of a better work, it’s a very difficult metal to die forge in thin cross section material. It CAN and HAS been done, but requires thousands of dollars in special dies. Titanium like to gall itself easily and "weld’ to steel. You can anneal titanium but that’s a whole other bag of tricks as it easily forms a surface oxide when unshielded. You need to spin it. It is the only way to achieve a proper, consistent, and good looking finish in the end. All are important because nobody is going to spend any money on a tip that looks like shit, especially one that costs as much as a titanium one will be. Titanium is not cheap, not even your basic 6al4v let alone some pure grade T2 or similar. Look up videos on metal spinning. I have the ability to spin some stuff on my larger lathe but my dies are specific to certain parts. You’d still need a proper set of machined dies and tooling to do this right, otherwise you’ll be wasting a huge amount of money. ---

I am going to look up some videos and check it out. I came up with an idea yesterday to make a simple geared turn table to chuck up a pipe and sping it around on my shop press. then make a simple die that would set screw onto the press shaft, then you can slowly apply pressure with the press while the piece spins and roll the lip inwards. Titanium is shooting for the moon, but I bet that stainless would be softenough to roll with my homemade lathe idea. who knows, its all just a search for ideas and knowledge really. Keeps my mind rolling you know. ---

Keeps my mind rolling you know. Stainless is harder than titanium. The chromium makes it that way. Spin RPM needs to be around 1500-2000. you’d be far better off buying a cheap lathe and modifying it to suit metal spinning than trying to do something in a press. Even a cheap 4-6" swing wood lathe would be better. ---
