      Flex pipe.. Why?

      I am noticing some builds are using Flex pipe. like this.. on RWD builds.. these were originally used only for transverse mounted engines since the torque of the motor made solid mounting an issue.. .. so I am wondering if I am missing something as to why this is a thing? It it just a trend or is their some material value for a RWD car that I am missing..

      I put them on mine simply to make it easier to line everything up when taking my exhaust system on and off. Also, my simple mind told me that I’d have fewer problems if things weren’t twisting against each other as they heat, cool, and torque twist around. The flex connectors were cheap enough to add in when I welded up my system.

      NVH for factory cars also.

      They're not a terrible idea.

      Along with the above they can also be used on exhaust systems with very tight clearances to the floor or body work. You can rigid mount the exhaust and put a flex pipe at the engine to accommodate movement.

      Allow for fine tuning exhaust routing, vibration doesn’t possibly break exhaust hangers, helps with movement if you bottom out some etc.

      Sadly, I found out the hard way that I still had vibration when I rigid-mounted my system starting a couple of feet past the flex connector. Once I got rid of that mount all my vibration went away. I still have my tailpipes rigid-mounted with no problems.
