If the chrome is gone, there’s nothing you can do to get it back. Your only options are to paint it, rechrome it (which is expensive) or just replace it with another stock exhaust. They are out there.

That’s a Minarelli pipe, not Tomos. Also Tomos a3’s absolutely came with chrome pipes. (edited)

Sandblasting won't restore the chrome. If you're lucky, it'll remove all of it. And it won't remove pits, either.

Sandblasting just removes paint, rust, and peeling chrome. It doesn't remove pits in hard metal. While it is abrasive, it doesn't sand down pitted metal to a clean, shiny surface. You'll end up with a dull grey pipe, that you'll have to physically sand a lot to make it smooth.

Either buy a better chrome one, or use a few coats of BBQ paint like everyone else recommended.

I have a tomos a3 stock pipe, they came in chrome and black depending on year and model.

Regarding the exhaust, Hit it with high temp primer, be patient enough to let it dry, hit it with high temp enamel, call it finished.

So I get that I can't remove the pits: what I'm wondering is how to best fill them so I can create the smooth surface you mentioned. S'all good if I can't get this back to straight chrome I guess, but if I'm going to spray paint it black or silver or something I'd at least like it to look clean.

Get it ceramic coated. See if powder coater can apply it heavy enough to hide imperfections. Ceramic is used on exhausts systems for more than one reason.

Just buy a new pipe. Your gonna want an expansion chamber at some point anyway..

Any filler if going to offgas and ruin your paint when it gets hot.

Really?? Come on man your smarter than that. Tell you what they have got an engine paint in cans at autozone every color. Withstands temps up to 550. Get a can of it and put 3or4 coats on it. It will make it look so good someone will ask where to buy 1.

toss it in thescrao pile.
