I have a 2014 Premier C7 with about 4k miles on it. It has the Performance Multi-Mode Exhaust System on it that I usually have in Sport mode. Standard tranny obviously. I ONLY run Mobil 93 Octane.
On the two outer exhaust tips I get a black build up over time that LOOKS like carbon. Anyone else have this? Normal or is something amiss?
The exhaust is routed only to the outer two pipes during start-up and cold engine temperatures. That is what results in the normal appearance of carbon build-up. If you stay on top of it, it actually is very easy to remove. Every time I pull RedHot back into her garage, I wipe the pipes with a microfiber after a quick burst of Spray Way glass cleaner (from Costco). They still look like new after 7 years!

Coke.... that’s pretty expensive. Oh wait... never mind, I grew up in the 60’s and 70’s!🤣🤣🤣🤣
