Stainless exhaust color
« on: 03.08. 2018 20:10 »
 Can anything be figured out by the color of stainless pipes?

 The bike has about 15 miles on it, and I will go another 10 than change oil and filter.

 Everything seems to be great except the front brake squeals so loud it's truly embarrassing.

 I have never had SS pipes, and don't know how to read into the color or if it's even possible. I know they turn gold, but are there shades of gold?

Hi Lee,
Nothing to tell from SS pipe colour as far as I know,
When a sufficient coat of carbon builds up inside the pipe you can re polish them and the colour will stay on longer
what fks them up is rain drops which results in splotches *sad2*

 No my friend,

 What REALLY screws them up is heat straightening,  followed by hydraulic bending.
 I have a bit of a Loch Ness monster going on the left hand pipe *eek*
 But I just took them down once fitted and had a re-polish done -they look nice.

 Now the damn poorly made hub cover came loose. Pulled over pretty quick for that noise. I have to figure out how to keep that thing on.

 Time to change out of the break in oil.

 Thanks guys,

G'day Lee.
The ss pipes I put on my plunger 35 years ago. In that time it was raced, daily transport, trail bike and tourer (two up). They are a little darker than new (never ever polished). Yours may be due to the thickness of the tube (everything gets thinner, smaller or cheaper over time, even US)!
Cheers

The oxide colours on a stainless pipe are close enough to the temper colours of mild steel.
On stainless they are a little higher but you can use them as a tempering guide just as you would on plain carbon steel if you are playing with a heat treatable grade of stainless.
The killer is they are much coherent that plain  steel staining so really need an agressive polish to clean them.

 If I would have thought of it I would have taken them down and got the insides ceramic coated before I ever fired them up.

 It took about 5 seconds to go from "looking like chrome" to gold color.

 I just wish more could be told by the color. Like with chrome, you can tell how the cylinders are running side to side, and if you are too lean.

5 seconds well spent, I prefer gold

SS pipes and silencers on my Guzzi Veefer are a light brown, I would hesitate to describe the colour as 'gold'.
