I would believe that its caused by the heating of the metal then cooling it quickly.
The quick changes in heat allows for the colour change in metal.

Nothing to do with how quickly you heat or cool it (you're not hardening and tempering for those who remember any metalwork from school), or whether it's done inside or out.
It's not what metal it is, although the type of metal will be affected by more by different temperatures.
Just heat it (a lot -- oxy-acetelene torch (blowtorch) is the most controllable, but you could stick the end in a campfire if you wanted -- ever stuck an empty tin in a fire?) and you are literally burning the metal -- that's what causes the discolouration.
It was probably done first by accident and now it's trendy...
this is a good question & it definately doesn't belong in the 'noob' section. if anyone knows how to do this then we don't have to fork out so much money for the Spoon titanium gear knobs
you mite get the look of spoon titanium but you wont get the same feel. I got one. Loving it!!!!!!!!!!1
... and you dont need to sell your ass or soul for it either... unlike spoon gear... :pQuote:

All stainless steel metals (all manufactured metals/alloys actually) are made up of a few different compounts, and as such, different percentages of different steel - this affects the grade of stainless steel, and the colour it burns.
Just stick it in heated coals overnight, or oxy-acetelene it (around the tip!)... Better yet, go and buy one from liverpool exhaust, they are getting cheaper all the time.
So has anyone done it yet to their exaust, i'm interested to see how it turns out
yeah ditto!
when they welded on the tip i notice that the effect on where the welds are are a blue burnt look like the blue flamed tip. I assume if you zap the inside with weld then it will do the same thing (can always grind off the weld). Or similarly heat it till it glows then let it cool.
we did it on my mates evo3 as the blue on the tip had faded over time. just used a blowtorch he had in his garage, turned out great. looked like it did as new :thumbsup:Quote:

my exhaust tips have got this nice black layer around the ends(rich fuel mix and launch controll spurting fuel), once the exhaust polished a bit with a wet towel they look tops!
