Race exhaust is too loud

After much thought I have decided to pull the Eisenmann exhaust off my M5. No doubt the sweetest sounding exhaust note I have ever heard, just too loud for everyday driving. One last sound blast around Willow Springs this Thursday with the evosport boys and off she comes. Anyone interested in it should PM me for details.

I would assume that this means the interior exhaust sound is a bit much for everyday driving? I love the exhaust note too, I just don't want it to overpower my interior noise... waiting to hear the SS Race.

Loud is relative. For me, this car is for hauling kids around town, and driving a couple of days each week to work which usually means talking on the cell phone. I notice the noise. Now, when you are concentrating on driving and/or at the track, it is beautiful music. I guess you can't have both and I prefer one over the other for my purposes.

I've found just removing the resonator is perfect for this type of driving. The exhaust is definitely louder, and under full throttle sounds incredible. But when driving 'around town' or cruising on the hwy, it's almost as quiet as stock.

The resonator/straight pipe conversion intrigues me, Wolverine. How does it sound outside? I need more aural stimulation inside for the track, but not necessarily outside.

Here is a thread where I compare the stock vs no-resonator exhaust. The sound is quite a bit louder under load, these files were made with the car at idle. Inside the car there is a definite increase at full throttle - certainly good for the track. It is only a couple hundred dollar mod - very easy to try - I would recommend at least giving it a shot.

Curious. How reliable are these dynos? I can't imagine if the car is running at 150 mph on a dyno, the dyno malfunctions and the car takes off. I doubt that chain holding the car will live through that scenario.
