Miltek - decat and silencer removal?

I have Miltek cat back exhaust.....
I'm considering having the cat taken out (2nd one only). But, i know this causes a flat spot. What i want to know is where. If its between 2 and 3000rpm that doesnt really bother me as i only use the car at weekends for fun. If its anywhere over 4000rpm then i wont bother.
Also thinking about taking out the middle silencer on the Miltek for bit more sound. Anyone done this before???

Cheers :smile:

p.s I intend on getting it remapped if i do either or both.
 
i have the ktec system with the decat pipe and my flat spot is between 2250-2500. can be annoying at times but if you drive 'sensible' you wont even notice it, its only when you boot it from low down revs its really noticable! hope this helps!
 
I have the decat on my miltek and recommend it! Noise is great!! Always pops on gear changes. Im tempted to have the silencer removed too....

Flatspot is around 3k barely notice it if Im honest.
