I searched the board and didn't find the answer to this, sorry if it's repetitive... but how do you get the end cap off of the FMF turbine core2? My Answer SA has allen bolts that you remove to get the end cap off, and you just pull the baffle out. The TC2 has 2 rivets that hold the end cap on... do I remove these rivets and replace them? If that's the case, that's cool, but I'm going to need to get a rivet gun and don't want to waste the money if that's not what I'm supposed to do. Thank you!!
