Plug: Robbins Wings

[John Courte]

When I went to install my heat muff on my 4-pipe exhaust yesterday, I found that one of the locking nuts for the through-rods had no threads in it.


I emailed Robbins Wings, and within 2 hours, Rick Robbins promised to send me a replacement. This is great customer service, even though my original hardware came through Larry Vetterman (who is also great to do business with).


Since we're on the subject of heat muff hardware, what's the actual name/type for those little hardened steel locknuts that go on the end of the heat muff through-rods?
