Hi all, I have recently rebuilt an engine to 1641cc and replaced the heat exchangers with j tubes as the bus isn’t used during the winter so heating was not an issue for me.
So my question is do I put heat wrap on the exhaust pipes or not? My thinking behind it is a) looks cool b) keep the heat away from the engine and in the exhaust itself.
Has anyone else done this if so does it work good or has anyone else got any opinions on it like it will keep the exhaust hotter for longer etc?
Any help or comments will be appreciated.
 
If you've got J tubes fitted get a pair of Butty's industrial tins.
Don't bother with exhaust wrap, it will only rot the exhaust quicker.

Heat wrap holds moisture and rots exhausts. Ceramic coating is a far superior method.
