MCX rear mount header and exhaust donuts

[judger101]

So i was thinking about replacing my exhaust donuts with the copper donuts for prevention. I was looking around and saw the mcx redline header with a lifetime warranty. This header doesnt use donuts at all.
It is only $400. Anyone have more thoughts on this or have this header? I was thinking for that price to just get this header and then never have to worry about cracks or donuts in the future.
