It allows as much, possibly more flex as the factory system would have. The factory exhaust is mounted to the transaxle via fixed brackets which allow very little movement.
The exhaust is supported off the transaxle which is directly attached to the engine and not the chassis, there isn't a significant amount of flex. The exhaust mounts to the headers via a donut shaped gasket and bolts with springs, which allows some flexiblity.
The heim joints at each end of the turn buckle allow the exhaust to move fore and aft freely. When the engine rocks front to back or side to side, the exhaust will follow.
The movement of the exhaust system due to heat shouldn't be extreme. From my perspective, the springy contraption Capristo uses poorly supports the weight of the exhaust system and may very contribute to the load placed on pipe weld joints and add to the deterioration of these parts over time.
I'm more interested in properly supporting the weight of the exhaust system and relieving the headers of that burden than allowing endless distance for things to expand and contract.
I found this to be a middle ground between the original fixed mounting and Capristo's complete floating system.
