Cat and Sensor on manifold help please

[Oxxmate]

Hey guys im thinking about changing the cat as ive got a loss of power somewhere and ive changed the filters, done the plugs, and my dad had this on his van changed the cat and it went back to its normal self. Well i was wondering if i change the cat would it be worth changing the sensor on the exhaust manifold too? as ive heard these are connected in what they do or something (im a novice when it comes to car mechanics) if it is worth replacing how do you take the sensor out?
any help apreciated
Thanks
Jay

The Lambda sensor can be removed with an spanner, although can't see how changing a cat can change anything, changing the lambda can do if it's been damaged.

If you're unsure why you're car is lacking power possibly may be an idea to get the ECU checked for any error codes.

ive seen cat's collaspe and lead to the car struggling.

Olly where would i get the ecu checked and how much you reckon ill be looking at?

remoe the cat and hold it pointing towards the light, looking through the hole. see if its clear of blockages.

you can hammer the interals out, can make the ehxaust note 'raspy' .... but will pass MOT emmisons ok.
