Cat bypass

I already have a tubi exhaust on my F355 but as some might already know, sometimes you just want more. I thought about replacing my headers with tubi headers along with cat bypass. My only concern is how this will affect my CE lights? 5-8 comes on every now and then but especially if the car is standing still but goes away when I start driving.

Ideas anyone?

 

I have a Tubi exhaust as well as Tubi headers on my 5.2 355. I kept my cats because on 5.2 versions if you fit pipes,you will trigger CEL.This is not the case if you have a 2.7 version.

I had gutted cats that threw codes and really smelled (spider with top down) Put hiflo cats and super happy, they flow great

 

Indeed life is good in a catless 95.....
