cat or no cat?

[aznbmxxxer]

is having no cat for a all motor car faster or slower? i recently put on my stock cat, and it seems that the rpm's seem to go up steady. when i didn't have a cat, the rpm's would go slower till it got to about 3000 and then it would just fly to redline. which one is better?

stock cat is always better, dont mess up the enviornment for a few horses

high flow best of both worlds

If it's a race car only (which your grocery getter probably isn't) then yes, it's worth a dyno-proven 6whp on a B16A2. If it's a sohc econobox used for driving to your $8/hr job, then no, it's not worth it at all because it will make your car sound horrible and will be illegal.

did the car loose torq when they dynoed it?
