The Monk 50 Posted May 29, 2009 Report Share Posted May 29, 2009 I have a decat pipe, the exhaust is not up to scratch though....example being, the join between the letterbox middle silencer and the backbox join isn't sealed properly, so I know the MPG will be slightly affected from leaking. I can't afford a new system atm AND to go to Bristol...but I also know the lambda sensors pretty much screwed and has been for months....hene the 14mpg average I've been getting.Will a normal lambda increase my mpg somewhat or will I need a wide band decat sensor?I know it's daft, but I just think, as the lambda is situated before the cat, that essentially the sensor will pick up what it needs to before the cat worked.....not counting back pressure.
