Has anybody ever tried using a flex connector in the headers to deal with the cracking issue? Or would a flex connector not hold up to the high heat/back pressure of a turbo system?

Just thinking about possibilities for exhaust stuff.

It should hold up to the pressure since the Mitsu Evo has one

The Evo does not have a flex connector before the turbo...

I've replaced many on the DC sports headers for the NSX. They heat up and crack within a year. I highly doubt they'll last very long on a turbo header.

I only do flex connectors when I build downpipes, unless there is no room, then I put them in the mid pipe.

Ok, thats what I was thinking. Thanks.

if these are stainless steel then they will not last in the high temp and oxidizing envirpnment. the only option would be to get a inconel material or other high temp alloy.

I used an inconel below style vibration isolator before my wastegate and it works perfectly.

I have one on my header. Local shop that welded it in said it would hold up in that position and they had used it in headers before (not 951 headers though).

IIRC the flex part was $50 or so.
