Soot on Rear Bumper/Quarter Panel

[MN Cummins Lvr]

I only have 3100 miles on my new ride and have noticed excessive soot on the rear quarter panel and bumper. I never had it on my 99 with 183K miles. I just thought the soot seemed a little strange because I have never seen any black smoke. Is this soot just part of the breaking in process?



Thanks,

Paul

I had the same thing, I think it's normal. I used some really fine steel wool get take it off the bumper. I think you can buy some spray that'll take it off also. If you get stacks, you will no longer have the issue.

A turndown will help with the soot and additional noise in the cab if you improve the exhaust system.

I use the Megs 4" Stainless Steel Tip from Geno's to cure the soot on the rear quarter panel and rear bumper on my truck.

MY 03 does it also.

I did the same. The Megs works (and looks) great. I extended it out about two inches past the old tip. No more soot.

Completely normal. Just wipe it off.

My exhaust dumps right in front of the wheel ... so it turns my wheel black. Kinda neat

My 05 did the same thing. I installed a 5" turndown problem solved

Mine did it when new, no bombs. It lessened some when I added mudflaps, but then seemed to spread it around more. It washed off with just the regular car wash soap, nothing harsh. Just a little more elbow grease, but nothing that I would consider a nuisance. Now that I have duals and more fuel, I get to wash both sides, but now I see it as a badge of power.

I noticed the same thing on mine after returning from a trip to Dallas. Took a picture and just haven't posted the same question you did. Thanks! I didn't think my truck smoked much either, but when driving a highway and going to pass someone, take a peek in your mirror when you punch it. Or simulate that same situation while your driving sometimes. She'll smoke until the turbo spools up... .

Mine does it too. Its black so you dont notice it until a wash job. Iv learned to wash the lower right rear fender last due to soiling my wash rag with soot.
