I have a 2001 accord ex 2 door and my cats starting to go. does anyone know if a highflow cat will cause a check engine light?

 

yea it will, the o2 sensor will be the cause. do a search for o2 sensor dofoulers on here

 

Thanks. is your car stick or auto? i was also looking for the best place to get a short shifter for my car

 

mine's a 5 speed, i actually have a short throw shifter and high-flow cat but not on the car, there was a discussion a little while ago about the best short throw shifter for the 6th gen accords

 

O nice. I'm new to the site. I wanna get a short throw but i dont wanna spend 70 on one. do you have the link to the discussion??? also i might just see if i can get a Honda cat 2nd hand from someone who changed their exaust.

 

it does'nt always set off the engine light, unless you have a 02 before where the hi-flow would be then you should be fine
