I bought myself a 530d here in Oz a month ago and have been looking for performance upgrades etc since.
I found a thread on another forum were the guy had removed the dpf and the rear mufflers with no apparent gain or loss of power and slightly increased noise. He had fitted straight through pipes instead.
Is this a known mod/improvement ?
We are not subject to Mot type inspections here ,only if pulled by the boys in blue and stickered.
I would appreciate any thoughts on this before I look deeper.
I will be tuning with a Bluefin superchip as I have one exchanged from my Megane Rs 250
All info appreciated!
