Hello guys,

Have any of you tried the fi valve-tronic exhaust system for our W204's?


To my knowledge, they also offer just a catback system which has the valves in the muffler. Does anyone have any thoughts on this system? Good/bads?

I'm getting my ECU tuned by Kleemann, and they recommend a muffler upgrade in order to bring out more exhaust crackles that they will tune into my ECU. As far as I can see, no other W204 non-amg's have the exhaust crackles and pops.

Thanks.

i haven't personally tried it, but i know they are good
