just installed my micron exhaust it has sounds awesome but now on the cluster the fi light is on, but i must admit it did sound much better with out any muffler on there at all, what do i have to do to make the light come off
The butterfly valve in the muffler is probably no longer hooked up, you had to disconnect it to get the stock exhaust off. Since it's not hooked up anymore, the ECU is freaking out and throws the FI light. You can buy a FI light fix kit from Muzzy's for around $30 that goes on top of the rotor unnder the tail plastic between the driver seat and pass seat, or make one. The exhaust should have come with an FI light fix, all major manufacturers are including them now.
