i might be picking up a comptech catback next weekend. what i wanted to know is should i get a high flow cat for it or is it already free flowing enough?
ive seen a few people on az with high flow cats with that exhaust but is it really needed?

 

It wouldnt hurt but its not needed. Id especially look into it if you have headers.

 

i do have headers.

i think i will get it some guys reminded me that im boosted so it would really help out with the blower since its pulling in so much more air.

thanks for the response.
