Hi I got my decat today and i noticed it had 2 lamba hole in it do I need to put 2 lamba sensors in it or do i blank them both off? also i havnt had a remap and im not having one soon will the car be ok?
Proper bargin! Tha lambda after the cat that checks the cat is working correctly - If you don't space it off you'll get a falt light on the dash. If you space it off it will remove the lambda from the exhaust flow so the car won't notice that the cat is missing. You can just get it mapped out if you don't want to space it.
I used to have no boxes when I had the cat but put the centre section back before the decat, its quieter than before and quite nice tbh
You need to man up tho, scared ov torque and now scared ov loud exhausts,
