My milltek has cracked twice where its welded corrision only 3yrs old and actually cracked at rear box now blowing utter waste of money. 
milteks come with life time warranty, give them the serial code and they should replace it, my mates one started cracking over 3 yrs ago and they just replaced it for him?

Waiting hear from awesomegti cost over £800 for milltek and APR d/pipe. Get it replaced and sell it lost all faith in it.
thats fair enough!
