Today I finished removing the stock exhaust manifolds and replaced them with a pair of ceramic coated ported and polished stock manifolds, which probably provide no benefit to airflow.

I also put one of the swaintech coated turbocharger inlet pipes in place on the BorgWarner K03’s to see how it would fit.

Because ceramic coating the inlet pipe is simply not going far enough…

I added DEI Reflect-A-Gold on top of the Swaintech White Lightning exhaust coating.
