what's going on with these exhaust tips?

Recommended Posts

So my exhaust tips don't look great. I set out to clean and polish them today but it appears they may not have intended to have been stainless finish...there seems to be some kind of black/glossy finish similar to the plastic look on the shadowline trim...

Is that even a thing? If so what to do? Presumably I could polish off whatever paint is on there assuming the tips themselves are stainless? Polish them up silver? 

Or am I seeing something that doesn't exist and they are just filthy :D

To me it looks like they are are chrome plated and the finish is wearing off

afaik they are stainless and the black stuff is just the carbon build up, and the grey stuff on top is just years of dirt and what not. it *should* clean/polish up nicely with elbow grease.

If it is chrome plated steel... then I would just get some new tips haha

Hence my confusion...it does in parts look like it's been coated with something...

I'll get the wire wool on it and see how they come up after a polish. 

Mistreated tips make me sad.

Here is a another view....and it really feels to me as if there is some treatment or glossy paint of some kind on these tips....they don't look *normal* somehow to me.  They look, black or dark grey...not how dirty stainless usually looks.

Mine did. Although one of the tips came off at some stage.

Ahhh so I'm not going totally crazy. That must be what these are. 

What to do..I've no idea how to refurb tips finished this way....doesn't look as if they are stainless underneath.

Polish the tips with Auto-sol Metal Polish. Good for headlight lenses too

I did mine with Autosol as well, worked well.  You should find they pull-off.  They do in the e60.  Makes it easier to do.  Then slide back on afterwards.

Yep all 135i's came with the black tips unless the car had the m performance exhaust installed. Then it'll be stainless
