Hi all,

recently did an exhaust pipe throttle body 'butterfly' valve to by pass exhaust gases from going to cat and muffler but instead expel out after the downpipe...

May I hear expert advise on whether doing so will richen or lean down the AFR during normal and wide open throttle?

Thanks in advance
