Exhaust Headers Looking a bit Worse for Wear

Surely black on the inside will promote heat transfer into the pipe?

That's what I'd have thought (not that it'll make a fat lot of difference - the heat will get into the pipe whatever it's coated with - a shiny coating might slow it down a few seconds though...)

Yes thats true..its a panigale exhaust which goes under the seat so should be a little cooler on the old bottom
 
If they are stainless go for Optiglanz from Amazon. Spray on leave 3 mins wash off....shiny pipes....the stuff is brilliant but be careful using it.
 
Brick Acid

Brick Acid is the way,

brush on,leave then rubb with scotch bright ( which will dissolve) or wire wool to get heavy stuff off, rinse with water.
then buff with scotch to matt finish or polish.

These were minging, took 2 hrs to get them up spotless,they havent had final rubb up in these pics.

Good old fashioned elbow grease and autosol:


......or a mate who is a metal polisher ;-). Blueing and the brown tarnish can be removed.
 
The exhaust headers on my 2010 GS are looking a little worse for wear - as in corroded not accident damaged.

What is the best option to replace? I don't want to de-cat or similar.

Are they pretty straight forward to swap - just bolt-off, bolt-on?

If you need new ones I've got a set in the loft that i was going to put for sale on here - if you looking for a set PM me, i will get some pictures, i think they've only done about 1000 miles then i went de-cat.
 
Oxalic acid is the one for cleaning stainless steel. Its not the most dangerouse acid about but you do need to take care as with all chemicals.
I use it to remove burns from welding on SS fabrications.
You can also get "Bar keepers friend" from most hardware stores and thats about 10% Oxalic acid and the rest is fine pumice.
It works very well just painting in on as a paste letting it sit for a few minutes and then washing it off. Itl remove the brown and
a lot of the stains. Use a cloth to polish with it and it works wonders. best part is its about £4.00 for enough to do twenty full ehausts.
Its also safe as houses once its washed off and diluted with water.
 
I have bought "bar keepers friend" in both powder and paste form................ I'll post up the results when I get around to using it.

Sent using hocus pocus........... boo!
 
Mine has titanium headers - Oooh!

Ive not tried anything other than elbow grease and Solvol but even the very tail end stubs are darker than the silencer can cases. The front ends are now very discoloured so will need some seriously hard work to clean up.
 
I take it , the wife was out when you used the kitchen for the exhaust make over:D

Good result though!....:thumb2
 
anyone else tried this

I have, it removes the worst of the brown but didnt get them anywhere near silver, or shiny, again. I only did them once though, maybe another treatment would help.
Having said that , the headers were really rough and needed sandpaper first before using the optiglanz. Its only a 250ml bottle so doesnt last long.
