Rear bumper tailpipe heatshield that screws to the rear bumper on the mk6 autospecialists don't do them anymore seeing if I have any luck on here

you'd have better luck and tbh a better result usually making one yourself from scratch.

 

Ive use thin gauge steel and chequer plate before and its relatively a simple affair to angle grind yourself a square and curve it to your bumper contours, then you just fire some nyloc bolts through it to hold it in place.

 

as a tip, avoid using the "easy fix method" of using self tapers or other screws as theyll gradually work loose as the bumper flex's through daily use and drop out...... along with your plate.
