I love the Cybox exhaust. Best sound improvement for the money. Even a muffler delete would cost about as much as this exhaust.
Cold start - very loud and deep note, just what you want
Slow driving at lowish revs you get a nice deep note thats not intrusive, also dropping down a gear with SynchroRev turned on sounds amazing. I do most of my driving like Miss Daisy now since I dont need to boot it to hear it.
At mid revs with a heavy foot it can be a bit too loud but if you dont need loud at the time you just ease off or change gear.
If you want to really scream then high revs and a heavy foot will wake up everyone (ive set a car alarm off with mine accidentally).
Cruising at motorway speed it almost sounds stock. Ive heard people complain about drone but there is zero drone from this exhaust if you are just cruising and maintaining speed. It only gets loud on the motorway when you are accelerating.
The best thing about this exhaust is how deep the sound is. And of course the price. I honestly dont see how anyone could have a bad word to say about the Cybox when you consider the difference it makes for the price it costs.
