to get an idea of how much front scratchers (FWDs) boucne about. go to your local test-n-tune with all the kids beating the fuck out their cars...its quite alarming.

the flex joint NEEDS to be located as close as possible to the motor to reduce the leverage on the rest of the exhaust, period. the further away it is, the less its able to absorb.

I've measured a touch over 2.5",on the rev limiter, of movement. With that being said it doesn't matter in my case since my roll mount will have been taken care of.

Yep, but you can't package a a flex joint in the location it needs to be in with joints that are a proper diameter.
