titanium exhaust piping

[prodigy]

As a matter of fact, i've browsed thru a few websites which said to be offering titanium mufflers. These mufflers are actually partially titanium only. Maybe just the muffler body or the tip and most of them are not welded, just bolted on or riveted together with stainless steel body.

question, y are there some muffler tip wit a slight pore on it?? wats that for?

 

[prodigy]

What do you mean by 'muffler tip with a slight pore on it?'

prodigy:thanks for the info.from what u said i dun think there will be available in malaysia soon and it will be fucking expensive to do it.im not interested in the colour of it,i only like the lightnest

u can check there is a broken ti muffler at JFA. no one can weld it back. normally they use the spring to join the titanium pipping with the stanless steal exhaust braket joint. thats why nobody will buy a titanium muffler alone.

Yeah, titanium composition is totally different from stainless steel, mild steel so if one smart ass says he can weld them together, he's bullshitting actually.

Again, titanium is very very sensitive to oxidation(rust). Thats why i highlighted the importance of using argon gas to purge and trail the welding area.

Hmmm...maybe its time i pay Jaaffar a visit.

errmm.... sumthin like the cf muffler, near the tip there, there is one screw or sumthin else.. not sure heard fr which party, sayin that will create the psshhh ppsshhh noise??! :Not_Impressed:

I don't know nuts about welding titanium but titanium doesn't rust in the general sense of the word. Titanium, like aluminium, forms a protective outer oxide layer that gives it a lot of its durability and characteristics.

Silverfish dude, my line was taken out of context.

"Again, titanium is very very sensitive to oxidation(rust). Thats why i highlighted the importance of using argon gas to purge and trail the welding area."

When i say titanium is sensitive to oxidation, i meant during welding period when the titanium weld is still in molten metal. Any metal, be it titanium, stainless steel or duplex steel will form oxidation when proper care is not taken during welding. Oxidation is a weak point of the metal when welded and within a short period, you find that the weld is not strong anymore. So to make sure titanium doesn't form oxidation, you need to trail the molten pool with argon gas so that it cools down faster and also no oxygen will get into the molten pool.

like that aaaa????
tq for the info

Mate, I'm sure you've got your facts straight. I'm just trying to clear up so that nobody misunderstands because of the "rust" word. Nanti they think titanium will rust like iron, and they go around telling people prodigy told them so, then jialat lor.

here's a review from another forum, hope tom doesnt mind

and prodigy, would you consider this a full 100% titanium exhaust? and it doesnt cost *that* much.
(25lbs for a complete catback system sounds...light)

it expen but amazing

:shades_smile: hi bro...it is exe but for those are using it...they can explain the diff...before and after...em...some people may thing that thats is cray but for the performance term it is ok.....:angel_smile:

From the article, it does look like they're selling full titanium exhaust. The article mentioned that its really light so i won't be surprise if its full titanium setup. However, one thing is that we won't know what grade of titanium is it. There are a few grades available in the market, and depending on your application, each has its own characteristics and its own price. I do think that for automotive applications, the grade of titanium are normally comercials ones. That means its the easiest to weld and most commonly found around. The ones that are used in underwater, heat exchanger or aerospace are alot purer and more expensive. Anyways, USD3K for a set of exhaust is really really expensive for an average Malaysian. We've not even put in the workmanship yet.

The main advantage of titanium setup is not the horsepower gain, rather the weight savings. The extra power you feel is most likely due to your car being lighter. If you ask me, a nicely tune up stainless steel exhaust can produce the same horsepower as a titanium exhaust.

Ah...the biggest difference is that you call tell all your mates that you've got titanium exhaust system.

 

[prodigy]

Haha, and thats worth 5 HP extra right?
