Hi Mike,
Below is some useful info I found regarding the HHR System.
Unfortunately I do not have sound clips at this time. I'm talking with R&D
to see if we can get another HHR in for actual sound recording. I will keep
you updated as it progresses....
Factory Interior DB level 76
Gibson Interior DB level 83-84
Factory Exterior DB level 82
Gibson Exterior DB level 91-92
The vehicle will experience a small amount of resonance between the
rpms' of 2,000-3,000 rpm.
The factory system flows 241.7CFM
The Gibson system flows 268.1CFM
The system was designed to not flow as much as possible but to flow as
efficient as possible providing good lower end usable performance.
Unfortunately I am un able to access the Dyno sheet right now but did
pick up 8HP and 10-12 foot pounds of torque.

I have since spoken to Felix and expressed that we would be happy to bring an HHR in and will even record the sound clips FOR them! They are checking with R&D to see what they can schedule.
Will keep you all posted as things progress...

Well.... that's a start! I tell ya- trying to get this info outta Gibson is like pulling teeth WITH A SPOON!!!
Thanks for the persistence, Mike. I'm still holding out for some #'s from Gibson... they're just too big of a name to pass-up purchasing.
As for anyone that has this system installed... (sorry man) TOKYO has one (pics shown in his gallery). Fitment and quality look superb
- however he has no way to get a quality sound clip at the moment.
KEEP PUSHING FOR MORE MIKE~~
