I currently run a header with a stock resonator and muffler I bought from Zygmunt. My problem is I keep getting stress cracks at the bottom of header. The header is not new but is not a rusty piece of junk either. I welded up the leaks Someone suggested worn motor mounts so I changed them too. Now I have cracks once again. Has any one used top end strut brace and torque strap? Is it worth the money? I don't want to have to but another header but I'm getting high off the cracks.
