Just finished another project. Ceramic coated the entire exhaust from the header pipe back. Also ceramic coated the exhaust tips BLACK. In addition, had a piece of aluminum fabricated to fit above the exhaust tips. Running with no muffler and rear cat delete, the heat was discoloring the carbon fibre. If anyone else is running this way, you should take a look. It also gives it a bit of a menacing look. In addition, I removed the muffler box that was still in the engine compartment. This does a couple of things. The engine bay heat now has a direct path out of the rear screen, keeping the bay cooler. You can see the pipes through the screen, pretty cool. And looking from inside the engine bay, it really looks good to see the exposed pipes.
