Thanks for that. Makes perfect sense!
On the strength of what you have said and your explanations with step by step instructions, I have ordered from the link you provided and will attempt to fit the s/s blanking plate myself when it arrives.
I will be having my DPF removed (internally) and deleted with an ecconomy remap after removal too so I should see some decent performance/economy gains when it gets done....
Glad to be of assistance,
You will notice a slightly more positive feel immediately after blanking the egr,
But the huge increase will be when you remap the engine.
I too would like to get the dpf internally removed but local specialist would prefer to manufacture a straight pipe replacement instead,
This won't make any difference to the end result except that it would be clearly visible "its gone"
I'm in search of a place that will do as I ask and remove the internals then refit the chamber not a straight pipe.
