Protection for new exhaust back box?

don't do short journies is the best way to keep an exhaust in one peace, if they don't get hot enough to evaporate any water inside it combines with the gas and makes acid which then attacks the steel allowing the rot to get going really quickly.

Thats mostly the reason the back box goes first, its the coolest part, if your worried fitting a stainless back box would fix the issue.

I've bought a decent rear box - Imasaf Oberst, made in Italy. They make OEM for Fiat and Alfa Romeo, amongst other brands.

The first and now the second back box have both rotted out along the pipe just before the box section. I might pour some high-temp paint down the pipe just to give the metal a little extra protection.

Cheers guys.
