640d sound + DP

[Mirinjawbro]

Hello all

is anyone aware (or if it exists) of a 640d downpipe which still has the dpf in place? does it exist?

also i've only ever had ress delete / backbox delete on petrol cars. is diesel just the same?

what's the best way make it sound "better".

there are a few straight pipe videos on youtube but will not spend £2k for some acrap ovic exhaust system


thanks
