I went a got a Remus exhaust for my 172, I dont like the duplex system so I went for the conventional twin tip style, same as the one on Yogis 172.
Thoughts:
not much louder than standard exhaust. When at Idle, u cant really hear it, rev to 2-3k theres a nice deep roaty sound to it. but over 4k the engine noise takes over, can only hear a bit of exhaust note.
I guess theres no noticable performance gains, purely for sound and looks.
Feel like a rice boy haha...
overall Im quite pleased with it.
