Black Soots From Exhaust all over rear bumper and trunk
#19
Well, I did not have this issue when i bought the car brand new. Few weeks after switching to FSport exhaust, I started seeing exhaust black dust all over my back of the car after about few days of driving.
To all, if you have a IS250, do you have this problem?

Another plausible reason for having dark soot on your rear end is from brake pad dust and the wind vortex created from the car's aerodynamics. It's very prevalent on white cars.
PLEASE take a picture of the areas of concern so that we can provide you with better insight. If there is dust all over the rear end vice just around the exhaust tips, it is highly unlikely that it's from your exhaust.

I think your speculation on the brake dust is a good one but not likely to be in my case. My wheels/tires are even cleaner than this. Also I use Akebono brake pads which has very little dust. My IS350 also runs on the same pads and do not have this dusting issue.

I have an 08 250AWD and do not have this problem,or havent noticed it. I have the no emblem fsport exhaust.
I drove from montreal to ottawa this weekend, and the usual, passenger side exhaust was black inside
I will keep an eye on it though. since the exhaust is black inside some of the soot should probably be getting outside in the air / on the car

Unfortunately quite common with DI gasoline engines. Those of us w/darker colored cars notice it mainly on tips.
Future DI gas cars in Europe might require cheap DPFs to hit emission standards.
