I bought an 05 636 that needed major TLC. After about a month, I have it ready to go back together. I started to install my Arrow exhaust last night. I put together the header, attached it to the collectors, and started to attach the mid pipe. I noticed from the mid to the collector that there is no room to use the stock gasket or clamps due to their size and no other hardware came with the kit. It doesn't have a spring connector that attaches the mid to the collector either. I have read in the past a few members have Arrow Full Systems on their bikes so any assistance would be appreciated.
