this is how i am going to connect the catback. There will be 1 connection at the end of the ypipe and 1 at the end of the muffler holding on the tailpipes. From summit collector rings are ~$5 a set, but i use 2 sets per connection, welding them togther doubles the thickness of the flange. The final thickness comes out to be 3/8+ thick. No way that will bend. This is how my current exhaust is setup and I have never had a leak. I am also using percys aluminum gaskets with a light coat of hi temp rtv. My headers use vbands
