BMS Chrome Exhaust Tips Turning Bronze

White340 · 05-18-2016, 12:26 PM

I have chrome BMS tips that are about 4 months old now and have about 2.5k miles on them. I've noticed that the chrome is slowly turning into bronze color (due to heat I guess). Anyone find a way to polish them back to chrome? I've used Mother's chrome cleaner on it about 5 times now (applied before taking the below pics), which helps remove the soot (needed after every wash). Perhaps this is what is making it turn bronze?

i got the matt black tip no problem at all

That's not unusual. Look at chrome pipes on a Harley, they not only turn bronze but close to the manifold they turn blue.

Hmm. what a bummer. I was thinking of ordering those but I don't want to have to constantly polish them to keep the color like my stock ones which are still perfectly chrome. This sounds like a defect. I would like to know what BMS has to say.

I am already on my second set of tips. The first pair I got looked used so they sent me another pair.

The chrome tips do need to be cleaned/polished every time you wash the car. It takes about 3-4 minutes to do and involves a good amount of elbow grease. The black soot from the exhaust sticks on it really well.

Well...even though they are supposed to be chrome, I like the bronze effect. Gives a nice patina that adds character.

Same like the stock ones...especially the left one. I clean my car 1-2 times a week so cleaning off the tips is not a big deal. Dis-coloration is. I use a metal polish cream so they shine up well.
Chrome turning going yellow indicates not a good alloy.

I'm quite sure that he's responsible enough to use re-cycled bath water. If he love his car that much he might even bathe in the water he recycled from washing his car.

This is a good argument for a sealant, like Menzerna PL. I wipe my car down with a microfiber towel when I get home from a drive, which gets rid of dirt and dust so effectively that my washing schedule has been cut by 80%.

Lol I use sealant RejeX. By far the best I have used.

Nevr Dull, works good for me

Most likely they are polished stainless steel not chrome plated & its caused by heat. I use this on my headers:

Wizards 11020 Metal Renew Liquid Polish - 8 oz

Wipe it on wipe it off, not much effort required.

Nope, only fresh water. And Every month my water bank balance goes up. I save water everywhere else so I can afford to wash my car often. I'm also really efficient in washing. Wiping the dust off with a towel after a drive...ouch...that's called saving water and making swirls. I'm going to sick Junkman on you
