I'll give them a few weeks to settle in (they look like they are a glass pack?) before I make my decision to keep the Prochamber and mid-muffler setup, or go back to the flowmasters.
Good deal. You will be having the m80's installed in place of the magnaflow resonators right?

Yup! I didn't actually ever see the Magnaflows in person, so I don't know if they look similar on the inside to the M80's or not. Hopfully they are different.

Ok, so after a few week so having the prochamber, I think I'm actually growing to like the sound. I still think it sounds really ratty when it's in the carport warming up, but once I get it out onto the street I kind of like it. It's alot more raw sounding than what I'm used to with the flowmasters, but I'm growing to like it.

I'm still going to try the pypes mufflers instead of the magnaflow resonators, hopfully they should be on soon.

Here's a clip of the setup right now, prochamber and resonators, it sounds pretty good when I'm out driving around in the mountains and such, it just sounds ratty when it's warming up, haha!

I have been told that M80 + SLP make a good midmuffler setup.

Ok, so I've had the M80's on for about 3 days now (with stock headers, stock cats, and prochamber) I'm in Phoenix for Thanksgiving, I'll be driving back to LA tomorrow, they have a nice sound with the prochamber, but the exhaust is pretty quiet now. Which actually isn't to bad for the drive to Phoenix. I'd say it's probably not any louder than the flowmaster mufflers I had before (with stock h pipe), and maybe even a little quieter? Not sure. Oh well, I'll wait and see if the mufflers get any louder over time, if not I'll try something different :-) Wonder if there are any M80's that are shorter? They seem to have a nice tone, but not very loud.
