When I was contemplating purchasing the sport exhaust for my Q70 I searched for a startup video for the 5.6L. I could not find one. I ended up purchasing it so here is a video of what the 5.6L sounds like with the OEM sport exhaust. Overall I am pleased with the sound. When I first got the car I was underwhelmed with the factory exhaust. It didn't sound as good as my '09 M45. The sport exhaust made it sound much better.

Is that the axle back system? Looking for a exhaust system for my Q70L 5.6.

Yes the OEM sport exhaust is just the mufflers/axle-back. They didn't make the 5.6L as loud as I'd hoped but did improve it some.

I have the sport mufflers on my 3.7L now and it made it louder than the 5.6L it seems.

Yes, axle back. Part number B0100-Q70SM.

I will note that listening to this on my laptop speakers doesn't really capture the sound
Listening to it on my iphone is much more realistic.

I have the Stillen Exhaust on my '13 5.6L M56S. Sounds great. Just the right growl w/authority.

I was looking at the Top Speed exhaust. Any info on them?

I contacted the intake company HPS I believe, and they said they are updating the intake tubes.
