Hey guys,
Couple of questions in regards to cats and mapping etc. At the mo, I have all 3 cats in place, haven't touched them... I'm not going to do go down the decat/sports cat route either. I do have a de-cat up pipe waiting to be fitted and I know the car will need to get remapped once it's fitted so that's sitting in my garage until i can afford to get the car mapped.
1.) Can I replace the cat pipe with a decat pipe (keeping standard up-pipe and downpipe cats in place) without a remap?
2.) When i can eventually get the car mapped and decat the up-pipe, so potentially only have the standard down pipe cat... will that be enough to get me through emissions?
Ta :D
