multiple brands over the years, they all cracked almost anywhere or leaked or both, its probably just me I am pretty ******* things (good old cast iron for me now)That's too bad.
What headers did you experience this with? Where did they crack?
Nice avator
I can say when I had my 4-runner years ago I had the TRD headers on it which is a good brand there headers cracked probably 8-10 times and they were under warranty so they kept welding them and sending me down the road after the 3 yrs warranty was just about to run out they had cracked again and they ended up giving me a brand new revised set of headers which had some kind of spring system design and those lasted until I rolled it upside down and just fubared the whole truck.
