2015 Lexus RC-350 Hey everyone first time here, So I already have a build for my exhaust and I'm stuck on the last step which are my Headers. Yes I am aware that I could just go out and get the PPE headers which is like $1,456.95 but I want to stay emissions friendly (For now). Now I am looking for High flow cats because the shop says they can do it and do a V-band but I need to know the question:
To the people that has their headers chopped off and replace with High flows, did you all went with 200 Cell count and didn't trigger a CEL? or went with a 300 Cell count?
I would like to know if the people that has 200 Cells, how was you're experience with it and what Modifications have you done?
Or any lexus in general that has High flows in that count
