Hey guys, if I missed a thread on this, apologies! Even just a short drive, I get exhaust soot running down the back as pictured below. Anyone have a solution? :)

Some spray detailer and a cotton rag. I give it a quick wipe-down after every ride.

It only really happens at startup. Most of us carry a microfiber towel to wipe it up. Since your car is yellow it is more noticeable than the dark color cars. My Mark IV red shows it too. Every few months I put some polish in that area. I do not have clear bra in that area because at the time the pattern used and the material were crinkleing up from exhaust heat. Not much else you can do. I have 6K miles.

Okay, thanks. Yea, I have PPF around the exhaust outlets and the soot is staining the edges of the PPF which doesn't come off quite as easily.

Only a little condensation left in the exhaust when first started, No Problem! Warm up after starting and a quick wipe and it’s gone! I do a quick rev before turn off after a drive to blow them out!
