Hartge quad exhaust conversion for 125i

[anthony.hunt]

Hi everyone

I am thinking of getting the Hartge quad exhaust conversion http://www.hartge.de/e/artikelpopup2911.html
for my almost new 125i cabrio and would be interested to hear from anyone who has already has it. The sort of questions I have are:

Does it sound as good as the twin exhaust does

Is it easy to fit

Does fitting it affect the warranty.

my guess is the bumper would have to be modified, but i wouldn't think it would affect the warranty

With M rear bumper they just add some plastic part and no modification at all is necessary.
I like Hartge exhaust very much.
