This is the Flip car we built a few months ago.
The customer wanted a little sound for more engaging driving experience.
We selected a Revel Medallion along with the LHT Airbox mod.
Part of the driving experience is sound. This dual exhaust looks and sounds great without drone.
We also installed the LHT Phone mount available here
