Does a F10, N20, 2014 have a seconary Cat. converter.
Hi, I just got a stage 1 chip installed, asked my mechanic about a catless downpipe and he said he needs to know if it has a secondary cat. I do not know, do you? Thank you. PS. once that is done he said I can do a stage 2. We are using RP performance from Oakville Ontario.
Thanks Sam
