I'm wanting to fit a sports cat to my R56 I will either be going for a evolve one or the milltek one, i'm currently running a milltek non res cat back. I know the sports cats quite often make the EML light come on. I'm mainly fitting one for a bit more noise, pops and a bit of a power increase, at the moment i won't be remapping the car so my question is it possible if the light comes on to permanently get it removed without a remap? Also regarding the evolve and milltek cats are they both similar quality or is one a better cat than the other?
Cheers
