As anyone removed completely the butterfly valve in the exaust and also the soleinoid valve that controls it? leaving the plug that connects to it connected to nothing.

just wanted to know if anyone has done this , do see if there as been any side effects

by the way the butterfly valve is still quite restrictive when on full open position inside the exaust pipe.

If you search you will see lots of posts on this subject,
The answer is,
1) yes removing it and plugging the pivot holes is worth doing.
2) No you cannot remove the solenoid wire without the EFI fault light staying on, there are ways of fooling the ecu to keep the light off but it's easier to leave the solenoid plugged in.

One major side effect I saw was improved fuel efficiency and power delivery.
