Recommended header thermal wrap ( not asbestos )

[Chinoi]

My engine now runs quietly and engine vibration was greatly reduced. My vacuum gauge reads 10 hmg when accelerating instead of 0-5hg.This means engine have better performance. Probably due to correction or alignment of engine exhaust port hole to header and exhaust gases now flow freely.

My only problem now was that exhaust pipe was too hot. Smoke was emitted in my muffler due to burning of previous oil deposit from my loose compression engine.
