2007 BMW Z4 M Super Sprint Race Exhaust
This is an A/V comparison of my 2007 BMW Z4 M Roadster with the stock Exhaust system and the Super Sprint race
mufflers and x-pipe I recently installed. The sound is deep. I apologize
for the poor audio quality of the driving portion--the GoPro HD Hero isn't
the best at capturing low-frequency audio.

As difficult it is to decipher the true sound of Exhaust on a video without professional audio
equipment, I did both videos at the same location using generally the same
camera and car placement.
As you listen, you will mostly note the higher pitch sound after install of
the x pipe. It is much more so in person especially since without the x
pipe, the very low frequencies are inaudible on these recordings.
Before x pipe, rear section was very bass heavy up to 3k rpm. Though still
bass rich, it now also has the change in tone to a higher, dare I say
trumpet like, sound passing 4k rpm.
Rear section was heavy in resonance in the 2 and 3k rpm ranges in cabin.
Its surprisingly a little bit less after x pipe install. But the whole Exhaust is much different and much more
characteristic in sound after x pipe.
I hope this helps anyone using these videos to decide on Exhaust for M3.

This is actually a review I filmed around the turn of last year, but never
uploaded. Guess its better late than never.
In this review, we get an up close and personal encounter with the 2007 BMW
Z4 M Roadster, in Black Sapphire Metallic, accented with the Light Sepang
Bronze Extended leather interior. This vehicle was kindly provided to me,
courtesy of our good friends at DFW Audi in Euless, TX (www.dfwaudi.com)
for me to review. This review is designed to provide accurate vehicle
information to both enthusiasts and potential consumers alike.
