Hey guys- I recently purchased a 2010 GT-R with 20k miles. Very good condition but the exhausts are just caked in carbon. What works well on this?

My tips get REAL black (the cars seem to vary from car to car on how black they get).

I use Nevr Dull to do hard cleans, then chrome polish on a polishing ball on a drill....once sparkling I do what other GTR owners have told me....a spray of WD40 (wiping off excess and what gets outside of the inner portion). After the WD40 all it takes is a wipe with a paper towel every few weeks and it comes clean.

What octane and brand of fuel do you purchase.

As soon as I switched to 93 oct, by Husky within one tank use my tips are clean and remain clean.

Just my experience from here.
