Removing the cat will free up more power than removing the silencer. Your car will have a lambda sensor fitted, even if it has no pre cats. In my experience, cats don't block up gradually, so much as suddenly; you'll know if its blocked because you won't be able to get more than 3000rpm out of it!!
