    Default clarification on cobra cat back exhaust

    sorry if this has been posted before but I just want clarification, if I fit a cobra cat back exhaust will my car require a remap? and will it effect the MOT? Also should I go for 2.5 or 3inch?

    You won't require a remap, and shouldn't effect mot as you will still have the cats in place

    Yes should give a nice extra bit of sound, especially being a cobra exhaust! Tend to be louder than other systems

    Don't be too disappointed if it doesn't give you the sound you expect!!. If it turns out like my Corsa, when i 1st put a Cobra catback on it was muted and didn't impress at all, then i started playing with the cats and that made the difference.

    even on the stock exhaust when taking both cats out and centre section its not overly loud and dont get any droning noises on motoroway.

    when hitting boost i do get a loud rasp but when driving sensible its not loud at all and pretty much every down gear i get a pop sometimes pop pop lol

    when booting it i get a flame on pretty much every gear change
