Worth it or not, depends on yourself.
Like what people said, why spending 1.3 mil on M3, instead of 1 mil GTR which actually faster?? same question

I am interested in changing exhaust for my E90 M3, but I am very particular about the sound. Do you think you can do a sound recording or a you tube of your car and the exhaust sound it makes in idle and in throttle? I've looked at other forums and in the US, the Active Autowerke exhaust is coming out and they claim quite a bit of bhp gain, so not sure about the Gruppe M one.
My wheels are being changed to HRE Monoblok P43, textured black, as we speak so can't wait. Just need to get the right exhaust note and I will be happy.
