well in the past 6 months the weather was less than 28*c
and this is the second exhaust which had been cracked
or it depends how hard you drive your F=P

 

mine was not titanium... the one in the pic is my midpipe section, less than a month old.

I got it replaced under warranty...

my friend just developed the same symptoms on his so he is fixing mine (the pics) until he recieves his replacement.
