i'd like to restore a rusty, but structurally sound, yoshimura exhaust. i've never done this, so what are the options? ceramic coating, powder coat, regular paint?

any help/tips/advice appreciated.

Regular powder coat will just flake and burn off. There are high temp powders available, but the results can still be hit or miss.
Ceramic coating is durable and looks great for years.
If you were to do it yourself, finding someone to sand blast your parts and then use high temp exhaust paint or even simple BBQ spray paint, is your cheapest and easiest option.
It all depends on what kind of finish you're after, budget etc.
As with all painting and coating, surface prep is key.

Having tinkered with doing this 20yrs ago, I never did quite find the recipe. PJ1, VHT, Tremclad BBQ, cooked in my Moms oven when she was at work or not, the result never lasted as I hoped, and never nearly as well as an original system.

I doubt Yosh or Vance or Hindle used secret paint, but my results always varied.

Now I don't know if this was because I applied it to a 2-stroke chamber, but once I just used the regular gloss black NON high heat paint on a dirtbike and it lasted way longer than any special paint on a streetbike. Ride duration, 2-stroke exhaust temp, sealing to head o-ring, I don't know why, but that old regular tremclad gloss black worked great.

Good luck, and if anyone succeeds with a rattle can solution that does a few years of riding and wants to showcase it, I'm all eyes.

thanks for the replies. i spoke to a friend who owns an auto repair shop, and he said ceramic coating is best. luckily, there is a local place he recommended, so my plan is to take it in for an estimate in a few months. i'll keep you all updated.

The longer you wait, the worse it's going to be. You might end up with a hole in the pipe instead of just surface rust.

Jet Hot coatings are great as well. they did a header and muffler for me for a little over $200. Unlike many shops they do inside and out to really stop the corrosion. Hard to argue with a lifetime guarantee as well.

Are we ever going to see this CBX project of yours? Must be a good 2-3 years now with no news.:dissapointed

Too many projects, the CBX is one of several. I plan on having the RC Engineering exhaust on it, ceramic coated.

I finally finished my '86 1100 a couple weeks ago, I thought that was good progress.
The Double is done and just waiting for good salt conditions.
A '68 750 Norton followed me home and jumped to the top of the "to do" list, it's almost ready for the road.

I'm currently working up at Baffin Island for a couple more weeks. When I get home, I'll do some updates.

Hey Marko. Nice find. I've been doing a lot of MX stuff lately. I have a guy that does repairs on old 2 stoke pipes that also works on 4 stroke headers. If you have really messed up ones, he can make them look right again.

But, for the most part, when it comes to the old bikes I work with now, I just have my chambers made instead of messing around with dented disasters.

I had an old katana that had a horribly rusted yosh full exhaust. I put it in a sand blaster, cleaned it all up ans sprayed it with high temp rustoleum primer and barbecue grill paint. If i remember correctly, there is a heat up cool down cycle you need to do to cure the paint once it's dry. After that I hit it with some high temp satin clear. Looked really good for a couple years. Then less good, but not terrible, yet not flaky paint/exposed metal. I think i went 4 years on that initial paint job before the bike became totalled

hey long and ragnar, nice to have you guys here.

long; i'm planning on getting back into mx, most probably vintage mx racing. i'll send you an email with my tentative plans.

i'll check into the sites/links soon, since i want to get this rusty yoshimura restored, in order to remove it from my lengthy "to do" list.

thanks for all the replies/posts.

Thank you, I'm often lurking, but should be getting back into it more now that I finally have a proper place to work and my 88 and I will be living under the same roof:thumbup
