I just swapped my catted downpipe back so that I can go get inspected. While I have the catless out, I wanna polish it up and make it look nice again. How can I polish the dp so that it looks new again? Can I use regular car polish or will that burn up when the heat gets to it?

Just take some sand paper to it to get the bad stuff, and gradually go with a finer and finer grit. Just be warned that the downpipe won't stay polished that long. It will start to brown.

Yeah it looks like crap right now. I just wanna make it look nice even if it's only for a few weeks. Or days.

I really wouldn't wanna spend 20 bucks on something I'd use once lol

I'll prolly try the sand paper and maybe a little bit of polish. I just want to get all the brown and black stains off.

fine steel wool might work pretty well too, like 000 or 0000.

You could always use it on your exhaust tip. Should last a few years.

well after wiping down the pipe real well, I think theres rust on it Shocked It's made out of stainless steel and I was thinking if I could use a ceramic coating on it to make the pipe last. I don't want to have to buy another Hrm

Not all stainless is created equal. There are different levels of thickness. I'm guessing that CHQ pipe is the thin stuff. But hey, for the price, it wouldn't be that big of a deal to have to replace it. Razz

nevr-dull will take care of any surface rust.

true that, but I like my CHQ...lol
I thought stainless didn't rust, no matter the thickness. I don't really know how to describe it but it looks like patches of brown/red that are on the pipe and they don't come off with wiping it down with Windex, nor a polishing compound (Meg ultimate compound).

you need to use rubbing compound, then polishing.

I worked @ a forging works company in the early '70's (yep i'm that old !) anyway I worked in the yard hauling in the steel by crane to machines a few years. stainless does rust.... the lower number grade ie: st 340 rusts quicker than higher grades like a 440 . Stainless would have spots while regular steel would be rusty overall . Just an fyi

An old trick we used to do to keep stainless and chromed pipes from discoloring by heat was to take the pipe and clean the entire inside with degreasers and high pressure water spray. Let it dry up, then spray in a can of high-temp exhaust manifold paint. Spray lots of thin layers first, then spray in an extra thick and heavy final coat and let the piping completely dry. Then taking a propane torch we'd apply the flame inside as far as it would reach to cure the paint for the next step. After cooling we'd spray a can of WD-40 into the pipe then assemble it into the system. Car would smoke like a bitch when first running as the oil is burning away. But the paint and oil cure to a hard gloss finish inside and prevented the chrome from browning or bluing from heat. I did this with a pair of Doug Thorley show pipes on my old '77 Vette. They stayed looking as good as day one when the car went 2 years later.

Regards!
