should know this cause i had it apart so many times, but don't feel like ripping it apart and measuring before i go to the shop...

what's the I.D. of the tube where the MAFS is? anyone know of the top of their heads?

thanks!

uhh...pretty sure it's below 3". i was thinking 2 3/4" or MAYBE 2 7/8".

 

It's 2.75".
