Good for what it is
Pros:
Deep grumble to the gr86 boxer engine
How the car should’ve sounded from the factory
Loud cold start that settles after 30-45sec
Mellow when cruising, comes alive after 4k rpm
Cons:
There’s definitely a drone at 2k rpms, likely pronounced due to the gr86 lack of insulation. Improved a bit with some sound dampers for cheap from Amazon
