This a question for the members outside the US.
Recently I bought a 525d E61 with the 3.0 ltr engine 197 bhp.
Planning for an aftermarket quad exhaust and remapping , I wondered how the sound would be.
Is it like a petrol engine or different?
Any disadvantages, like loss of power in the low powerband?
Your replies please, I'm curious.

on my (now crashed)525d i had a eisenman. You dont hear anything....exept on full trotle respons in low rpm you here a very cool V6 grouming on a low bass frequency. I kinda liked it. Not to disturbing but with a very sporty feeling about it.
I am hoping to save up for the hamannn quad witch i think will be even better on my lci 525d i have ordered

A little different : you can put a less strangled (than stock) exhaust and, in theory, you should gain something ... But I know there are some filters you haven't unmount, otherwise you risk to loss A LOT of power .
(my map-man has a 330d E90 ... He tried to take FAP (or another filter, I don't know) away and he lost power .
