im thinking of having primary cat bypass on my CS,..
i was wondering if it works with the CS, or it does only with the turbo??
need your opinion,, i live in jordan, so it doesnt matter about air polutoin...
let me know ,. thanks

 

Hey there,
I think you'll lose some back pressure, which would kill some of your low-end torque possibly. You might pick up some top-end horsepower though. Exhaust sound would increase as well. Let us know what you decide.

 

mine are cloged, due to bad gas here in jordan its an 05 CS, u think if i got a pair of high flow cats is better? keeping the low end torque.. cause im not gonna take the risk of empting them..
if ya, where can i get high flow cats thats not expensive..
thanks for the reply 03evoIII
