I just put the full cat back supersprint exhaust system on my 650i. It installed with no major problems, sounds great and the throttle response is improved.

Interesting, I'd love to hear the sound. :thumbup:

You need to drop that thing! (don't forget, with coilovers and the M5 wheels you will need about an 8MM spacer in the front)

Are those the exact M5 rims specifications? How do they feel? They look good. Can you post more pics of the car & rims? Thanks.

Is the 2 in-2 out muffler shaped piece after the cross bar the resonator? What does it do and have thought about removing it? People have mentioned that it sounds better without it. Where did yo have the work done and the cost?
Thanks

It's the deframinator that keeps the flux capacitor from overloading when you go into warp drive. DO NOT REMOVE IT! It could be the end of the universe as we know it.

Here is the exhaust system from supersprint spent about 3k, regarding the M5 rims, they are not the real ones from BMW, they are factory replicas, they fit my factory run flat tiers no problem, and are alot lighter than the stock alloys.

Great choice man. I have supersprint both on my M5 and 6 Series.
Hi Hamann6,

Where have you been? BTW you still owe me a soundclip of your Supersprint exhaust:D Since you have the supersprint on your M5 and 6er, you owe me 2 soundclips :) I'm now planning to replace my eisenman with supersprint M6 racing mufflers

No. An accident ran into him. I would like to get my front bumper re-painted from a few kisses before I figured out how to turn the PDC on without first going into reverse. And a couple other spots, too. Without it being a MPA (major pain in the arse). Anybody know a brave and steady-handed touch up artist in LA County? Who makes office calls?
