their White Lightning (TBC-EX) Exhaust Coating on the exhaust manifold on my MR2 Turbo and have been really happy with how it has held up. I've had it on the car for 4-5 years (a track car, although it hasn't seen much track time in the last 3 years). I've seen many other brand coatings that started peeling on just turbo downpipes, much less on exhaust manifolds, so far no issues with any peeling or flaking off on my manifold.
