123D Dual Exhaust Upgrade, Help!

Hello,

New member and new owner of a 123D, loving this car and wanted to get a few upgrades. Hoping someone could help me out!

Looking at getting a custom exhaust system fitted, have a quote for a Kerscher 1m rear bumper and quad exhaust system. The entire exhaust system will be built by the garage as Milltek have stopped production on the 123D quads.

Q: Is it really worth putting a custom exhaust system on a diesel?

Q: Due to a custom job, silencers will be an extra, what's a good one for a low yield sound, nothing too aggressive but something that actually lets you know your doing 100mph.

Q: It's loud enough as it is inside the cabin, will a quad exhaust system make this worse?

Q: On a custom setup, can the DPF still burn off soot adequately like BMW's stock one?

Regards!
