have a fully decatted system all the way thru, d/pipe, up pipe, manifold, centre and rear sections.
do i need to keep the lambda seneor as there are no cats ?
someone please explain and the more detail u go into the better for me to understand thanx.

 

I would unless you want your fuelling to be messed up, I certainly wouldn't advise leaving it out.......

 

Agree there, the Ecu uses the Lambda with or without cats.
