Here's an interesting question...

As some of you may know I installed a SC kit and exhaust this past winter. What I've noticed is that even after a short drive the back end of the car, rear bumper and rear decklid under the spoiler, has some metallic substance all over it. Very fine like dust, but something metallic.

I did a compete visual inspection and I can't see anything rubbing metal on metal and there are no sounds to indicate metal rubbing.

My question is, could this be residual debris from the new 200 cell cats that are burning off?

Sounds like whoever fabricated your new parts didn't bother to clean metal shavings out of the parts before final assembly!

 

Sweet! haha wonder how long it will take before that gets all blown out.

Only you have the POWER to decide that! just remember to hose off your **** before rubbing to avoid scratching it!

 

haha I've been working on it!

Yup I know, I make sure to hose it down a lot before washing it.... bit of a pain.

You sure it's not just dust from the belt?

Maybe reinforcement fibers of some kind?

 

Could be dust from your tires. It looks a little metallic.

 

when i had a MINI S, i put a miltek exhaust/cat on it and had the
same fine metallic dust all over the rear for 4-6 weeks then it stopped.
