Exhaust water steaming

[antreas typer]

I have noticed that almost on every ek9 with mugen twinloop exhaust system get from behind a lot of steam even when the car is hot or cold. What makes this happen

Maybe because you have a longer run of pipe so more cold area to condensate against?

Most likely try have also got a decat fitted, every car I've fitted a decat too then steams from the exhaust even when at full operating temperature.

Mainly noticeable in the evening / night and only when the car is idling

Mine is the same decat header twin loop, and steams like a mofu,

Mine does too, full 5zigen with decat.

Mine does aswell I have a decat but still have a silencer on the mid pipe, always thought it was because I have a upturn back box
