Would anyone know the pipe inlet size to the R18/Non-Si muffler?
 
on the 8th gen...another member measured it. I'm sure it's probably identical.

"It measures 1.915" in diameter using a dial caliper"
 
hmmm, Im working on a custom piping for a cat delete and exhaust swap. I'll double check tomorrow when I grab a caliper.
