Major warpage at the triangle flanges, I still have major exhaust leaks after installing them with Z1 gaskets. I obtained these from a buddy who always knew he had this problem, but he recently moved on to test pipes. Once I got them you could see the black carbon build up in-between each bolt hole where it was leaking through. Just looking at them you could see how warped they were, no QC dept? You can hear the loud raspy leak under the car at idle and especially under load.

So has anybody had any luck getting them machined?
