well here is some pics of my painting process to reduce heat,
1) First coat on the resonator u-pipe thing
2) Finished practice
3) Covered up bubbles, i think i only did like 3 or 4 coats
4) The painted cheap intake with like 5 or 6 coats on the outsied and 3 on the inside.
5) Before it was painted, big difference i think it looks much better
