When swapping the muffler on my ported 2166 the one I was putting on needed the bracket that came with it. I tried the one from the 2166 and there was a gap between the bracket and tye chassis. I was under the impression it was a 372 muffler, but I'm not 100%.
@mdavlee this was on the one I got from you, anything to add, was it for sure off a 372.
Also want to ad that the mounting plate on the 2166 muffler was thinner than the one I replaced it with.
Dan I think I have a new stock jred muffler here with the bracket, want me to put it in the box.
