Removing CAT
 

Hello everyone,

Just a quick question with regards to CAT removal, I only have one CAT remaining on my car, and I want to remove it, I'm just wondering will I need to remap the car? My car has already been remapped but does removing the CAT affect performance? Many Thanks.

Yes, it will need to be mapped as it will be all over the place and would/could the engine to go pop.

Best thing to do is get all the parts you wanna fit then fit them and then get it mapped.

Do it once and do it properly ;)
