There is a valve on the exhaust that would need to be removed when I am installing the Big Radius.

When this is removed it can give error messages on the EFI system, any suggestions on how this can be circumvented?

Sounds like you are talking of the o2 sensors. They should be able to be installed in the new pipes. If you do disconnect them you will get codes and the eng lite on. The BR pipes have bungs for these sensors and if not using a fuel control that doesn't use the o2's like a PCIII then I wold install them.

 

No this is a valve, like a butterfly valve, you can actually see it move when you throttle up.

 

yes i saw that in my manual. it is an option. you wont use it any longer when you change pipes but i donot think it has any electronics that would cause an error code but i will look, it is called active exhaust and it has no electronics
