I haven't found anything that'll stop the pipe going brown. 'Brasso' will shine it up, but as soon as the bike's warmed up, brown again..... :cry:

When you wash your bike go over it with a brush and it will get the baked on dirt, off your pipe. Not hard to do at all....

If you really want to use WD and some fine grit sand paper. That will basically make it look the way it did originally.

The headers not going brown, its the mid section and on my WR the Silencer / Muffler. I thought the mid section was stainless on the YZ.

Okay you have heard the rest now hear the best! JK my fellow TTers and YZ450 riders.

I detailed cars for over 4 years and now I'm a welder / fabricator. So I know a "little" about cleaning and a "little" about metals such as STAINLESS steel ( my favorite metal to build with )

Stainless will turn blueish / purple when extream heat is applied such as welding or exhaust from an engine. Thats normal.

If it has a brownish tint its either mudy water thats been cooked on it or it rust due to a low quality of SS ( which is not the case on your bike ) or its rust from you tring to clean it with a mild steel wire brush. The brush has contaminated the SS with mild steel, which will rust when exposed to water. It will look clean and shiny for a day or two but the rust will set in. You must use a SS wire brush to remove the mild steel or mudy water contamination from the SS.

Stainless steel comes in many different series from 200 - 347 all depends on the chromium % and the nickel % that is added to regular mild steel. Thats why a low grade of stainless WILL rust. A simple way to see if you have a higher or lower grade of SS is to see if a magnet will stick to it. If a magnet will stick it has a low percentage of chromium and / or nickel thus it is of low quality. If it will not stick it at least around 300 series.

My advise is simple:
1. Remove the top layer of metal with a fine SS wire brush on a grinder or alot of elbo grease.
2. Polish with "Never Dull" an Eagle One product. It comes in a silver and black can. It will take many steps of polishing and buffing but the shine will last forever until it is scratched by something hard, but scratches can easily be buffed out.

My stock YZ450 muffler has a mirror finish that I can fix my hair in. Never Dull also works great on aluminum like the little frame that hold the rear fender, also like glass on my bike. :cry:

I'm sorry I thought we were talking about the muffler, which is stainless. The header pipe and mid section is Titanium. The brownish tint in your mid section is normal from the heat it just not as hot in the mid section as it is at the header, which has a purple tint. If your mid section were ever to get as hot as your header pipe it would turn purple too. Titanium looks alot like stainless but darker. From a hottest spot to a cool spot Titanium goes from red ( almost molten ) to dark purple to light purple to purple/browish to a dirty copper color.
Titanium has an excellent resistance to corrosion. Its heaver than aluminum but lighter than steel. When titanium is annealed, it is relatively soft and ductile. It obtains maximum strength when it is solution heat treated and then aged. Strengths can exceed 200 ksi. It come in four different grades, ASTM Grades 1 - 4.

Stainless is a Ferrous metal ( contains iron and steel )
Titanium and aluminum are Nonferrous ( does not contain much iron ) which is why you will never see rust on a nonferrous metal.
