Superchargers produce a fair bit of heat if the manifold to the ports is restrictive but the Rowland for 180aud is worth the investment. The exhaust also gets a bit restrictive to expel the hot gases and a reason simple powerups on NAs usually aim for at least vanette rather than GX headers.

The rowland manifold makes mounting the supercharger easier and has a better larger inlet to match the sc14 than the stock little stocky.
