Just hooked up the FMIC to the inlet with some piping which came through the post for my cousin. I just did it to check out what it would be like, and if I like it I will get my own piping.

Can't test it out yet because its daylight and the cars not got much petrol! Sound wise, it doesn't sound better than an open cone filter. Its quiet but I don't know what its like on the move. I will report back once the performance
