Has anybody's headers here every cracked from hf cats/test pipes that weren't mounted on to the stock brace.......I was just reading an old post wher esomebody was theoretizing about how it'd be possible for aftermarket headers to crack if the rest of the exhaust isn't properly supported......yet I've read countless posts about many brands (crawford, kinetix, etc...) hf cats cracking when used with the stock brace, hence why they removed the brace support from them.
