I WRAPPED MY EXHAUST ON MY BMW 3 SERIES E46

[@martinp8427]

Shouldn't you wrap the exhaust manifold in order to decrease engine bay temperatures and use all of the benefits that the wrap provides? Why did you chose that particular section to wrap in your video?

I'm working my way to the front. Granted I should have worked front to back but I'm just messing around at this point 😁

[@Falco_e46]

From what I‘ve heard you should wrap up until the cats since it makes those more effective (and headers since those get hot af), but afterwards no wrap is better for flow since when stuff is hotter the air expands and it needs to travel faster meaning more friction

Thank you for the advice 😁

[@slothgarage]

Even if it hasn’t made a difference, it looks cool 😂

[@gazza9919]

Yeah that's the main thing 🤣

The headers are cast iron if you're using stock ones. Do not wrap them.

[@gazza9919]

What could happen if I do?

​@@gazza9919they will crack, so unless your planning in replacing them...

@@momfiethehunter504 I'll avoid touching them then. Thanks for letting me know 😁
