Rusty Exhaust Pipes

[michael816]

Anyone know how to remove the rust and prevent it from returning?

Once the rust gets to that point it's almost impossible to get rid of it. Your best bet is to find a sandblaster in your area. I've heard good things about ceramic coatings but they are expensive. Not sure what your budget is.

Well I was hoping for an easier solution, like a gel or cream that dissolves rust and polishes the chrome. I guess you cant always get what you want.

Jeez, you live in texas, isn't it as dry as a recovering alcoholics palate there:-D
Naw, your rust problem is about as bad as I have seen, if you use naval jelly or sometning similar, you will still need to do something to seal the metal again, coating or paint, because they will look like shiite once cleaned.

In the uk we get more rain in a week than yo guys do in a year so rust is a very big issue here :shock: What ive seen alot of peeps do is remove as much rust as possible with chemicals/abrasion etc then peeps would get tins of ......wait for it......BBQ paint :-D To repaint them? Ive seen the results and boy it looks good,matt black and the rust would have a hell of a job returning thu that paint\\/

To remove the rust, soak pipes in Evaporust. Check it out at: http://www.evaporust.com/

It's available at Autozone and it works! You'll probably need more than one container, though.

Phosphate washes work pretty good to get through rust. I'd recommend using something like that after it's blasted because it will get into the pits in the metal and leaves the metal with an iron-phosphate conversion coating which helps retard rust. I've used Jasco products for this type of work before - Metal Primer and Metal Prep. Used to be available through Home Depot and Lowe's but I haven't seen it there lately. I've heard of people using Behr Concrete Wash which is a phosphate wash for this purpose also. Not sure about concentration issues though. At any rate, this is a good follow up step or you can go straight to it if you find a good solution and have some way to keep the metal wet for a couple of days - use a paper towel to keep the stuff on the surface wet. I recently soaked a rusty starter cover in some Metal Primer and it came out pretty clean - with a nice dull gray cast to it indicating the coating has formed. Not sure how you are going to manage that with some headers though unless you are very patient and buy the stuff in gallons.

Evaporust is great and I've used it alot for small pieces. However, at $9.00 for a 32 ounce bottle, it's going to be pretty expensive to get enough to submerge those pipes?

If you want to leave them on the bike and clean them fairly quickly, so you can keep riding, get an assortment of wire brushes that fit your drill and have at it. Several different shapes are better so you can get into all the different crevasses. One of mine was pretty bad, and at least it made it look a LOT better. Wire brushes, don't seem to be recommended very often, but if it is that far gone, it won't hurt.

Good Luck

I used the stovebolt.com derusting method and it worked very well.
Started with this:

And ended up with this. It's raw steel where the rust was so you need to paint it when done. Costs about $10.00 for the setup if you already have the battery charger.
