Looks like your message got cut off - but to answer your questions...
This is the Zoomers cat back system for the '07 Tahoe. (I think the part number is API-1015-07 if I am reading the invoice correctly). The system came with EVERYTHING needed for installation and after removing my factory exhaust, installation of this system took about 20 minutes start to finish! The system is set up where it uses all the factory rubber mounting points and fits like a glove with pleanty of clearance around suspension components, heat shields, etc!
(Also included in the package were full installation instructions and also of note - the pieces were VERY well packaged!!)
From the functionality side, I am definitely looking forward to seeing what type of an improvement it makes in the highway milage, but from what I have seen thus far, with it appearing to be staying in V-4 mode more, it should be notable!
Also - I do have to commend Zoomers on the fact that the system definitely lives up to their claim of no drone. I have noted NO drone or resonance at any speed/rpm, whether it is in V-4 or V-8 mode! This was one of the things that I researched prior to purchase and is part of what led me to choosing the Zoomers system over some of the others current available out there.
Needless to say, I am VERY happy with it so far!

I have a white Tahoe and am seeing the exact same thing. Doesnt have anything to do with how far or long you drive it. Mine is covered with the same thing. I suspected it was exhaust and dirt "flow" around the rear of the vehicle.

My other question was if it was cat back. You answered that.
So, you haven't seen much difference in the way it sounds? I'm not looking for sound. I would like it to be about the same. I want to have a little more power, but what's most important is stay in V4 longer to get better MPG. I'm at about 17 now mixed, but I would like more.

Times must have changed at Bose since the '02 TrailBlazer came out. Mine had a Bose system that had an "Auto Volume" function that sampled the interior noise level and adjusted the volume to match the original level. Never worked. Chevy replaced the head unit to no avail and then told me it was working as good as it could. (which was imperceptible). Bose told the service tech that the amplifier max input for this function was 30 millivolts. He measured the microphone output and it was 30 millivolts. This means the ampl was always saturated and couldn't function as intended. I suspect Chevy substituted a cheap mike for the one Bose spec'd. Tried to contact Bose to no avail. My 2007 Tahoe has SCV and at least it actually varies the volume level. Honda used to have (and maybe still does) a auto-volume system that detects cabin noise level. Do not have personal experience or know who makes it but I'll bet it works. Good luck! Let us know what you find out. Does this mean my Tahoe doesn't have the subwoofer?

Was there any noticeable sound level change at idle, part throttle, and full throttle? Did you buy direct from Zoomers or somewhere else? The picture on their website looks like you have to cut existing system behind flex joint and then clamp it. Is that accurate? Thanks.

I hope your Bose Amp is not the same one they put in the new Impala. They had to put out TSB about replacing the Bose Amp for being "hissy".
Does your 07 Audio system has Bose amp option? If not, the SVC is done by the Head unit

Supposedly the Bose 9 speaker system (incl subwoofer) is standard on the LTZ. I sure don't know where the subwoofer is. If it's in the console, it's well hidden. As far as my 02 TrailBlazer goes, the Bose system in it worked and sounded very good. Just the Autovolume didn't work.

Does your truck have a center speaker on the top of the dash? I'm thinking that might be an essential part of the centerpoint marketing? My 07 Denali has the center speaker and I do have various sound fields I can access such as driver, surround, back and so on. I do have audiopilot and it seems to work fine without issue.
Do you have any of the same functions/setup?

No center speaker. Appears to be 2 tweaters in the A-pillars, 4 speakers in the doors, and 2 speakers in the rear corners (D-pillars ?). So maybe there is a subwoofer hidden somewhere. I realize you can put one anywhere as lo-freq sound will travel thru things but on the subwoofers I've seen in home entertainment systems always have a grill opening.
