I plan on fitting a resonated x pipe, as for normal driving it can be too loud and tends to drone.
Loud is ok (once it's not wake-the-dead loud) but drone wouldn't be cool.

It's strange I thought the reason you pay a lot of money for the Eisenmann was because there isn't supposed to be any drone, but a lot of people are mentioning drone on forums, someone on e90post even offered to drive to people and show them how much drone their was to persuade them not to buy it.... I wish there was someone around here with one fitted so I could see what it's like in person! Hard to spend circa 1.5K for something without seeing what it's like first!
The drone from it was atrocious. If you didn't know if cost a lot you'd assume it was cheap crap.

While it didn't wake the dead it did wake our baby on more than one occasion.

I was only too delighted to take £1k off a guy on m3cutters for it and return the car to standard
