Exhaust

Seems to be a lot of confusion over replacing the Exhaust on a Puma 2.4 2010 Defender, i.e. De-Cat or not to De-Cat?? Being New to Forum I'm still in the infancy stage, So can I ask those who we must bow down too!! for the correct info!!!

I have a 2010 Defender with a 2.4 Puma Engine, That I've been told it does and it doesn't have a DPF ?? "only hearsay your honour".
QUESTION IS
Where cam I but a Exhaust Downpipe??? please only answer with Part Number and Where to purchase!!! no might have a DPF, Might need a DECAT !! never had a cat, Hate Cats make me itchy
