I honestly thought maybe someone maybe did that to make them fit on install but looking at the second pic on their website they do indeed come flattened.
I wouldn't want that, but I do remember that episode of engine masters where they smashed the headers with a sledgehammer and saw little difference in power output. That was on the primaries, and I'm sure post-collector there is a bigger effect.

It's there to reinforce the body and reduce chassis flex. Could always put it back on...
I fully understand the reasoning behind it. I just don’t care much for it. There was just no way to keep it with MBH setup and I didn’t feel like adding washers to it. Maybe one of these lazy Sundays I will as I saved all the accessories.
Taking it off is better than smashing the exhaust, would be my point I guess. That just looks, well how it looks.
Edit: Just seen the post showing that this is how they’re made. I thought they were smashed in by the mechanic. nvm….

CKS headers with the front pipes clears the bar, and isn´t flattened(3" diam).
Just a well done bendingjob from the manufacturer does the trick, no spacers needed. https://www.cksperformance.com/produ...hausts-headers
