Just the default chrome, dipped them red with a gloss coat. I didn't do too well, but its hard to see, when it comes off will redo properly. Looking for red ones to replace but they all are overly designed.
I join the proud list of MMS owners. Added some red highlights to add a splash of color (and sporty feel). I need to make the muffler chrome red too at some point.
Love how reflective this color appears to be.
