Hey yall,
I finally got the flows on.
They sound great. 
I thought my buddy said he had the whole cat-backs, but they were just the mufflers which worked out really well. It only took me 30 minutes to jack the back of the car up a little, cut the stock muffs off, clamp the new muffs on, lower car, and clean up. I will have them welded soon.
One thing is strange, they are only slightly louder than stock at idle, when you're behind the car. They are actually quieter inside the car at idle. They are nowhere near as loud as the stock exhaust when driving and I HAVE NO RESONANCE AT ALL!!!!!! I thought my stock GY run flats were making all of the noise while driving, apparently not, it's significantly quieter on the road now. EXCEPT at WOT, then they scream, much louder than stock.
They do not sound anything at all like any of my muscle cars, and I can't get over how quiet they are. I'm happy with them even though they are not as loud as I was hoping. They can stay for a while.
Hmmm....
I wonder what they would sound like with some long tubes and no cats?!

I've always been a big fan of Flowmasters. Loved them on my Mustang GT. I even have one on my 93 Eagle Talon Tsi and it sounds great. Thats my opinion. The Flowmasters are real throaty which I like. I personally do not like the Corsa and Borla sound. Kind of tin canish to me. I'm sure I'll get flamed on this one. Thats just my opinion

Flowmasters are the best sound on a Corvette. My ZR-1 is the best music anyone can hear. The thing is that only those left in my wake can hear the roar at WOT. The car is very quiet on the inside. I have headers and cat back Flowmasters. Not at all tinny like corsa. I love the Flowmasters for their unique sound.

On C4s at least, the Flowmasters were more throaty and rumbled. The Borlas were brash and unpleasant, to my tastes.

It is not a bad mid-range sound.

When I purchased my '00 about 6 months ago it came with a flowmaster exhaust. I replaced it a few months ago with a new Z06 ti exhaust. The flowmasters sounded good, very deep, loud at WOT and just a rumble at idle. What I did not like was the appearance, the tips were too small and I did not care for the dual tip oval. Also, the black spray painted cans did not look that good although a re-spray would have temporarily fixed that. BTW, the flowmasters are still sitting on my garage floor.

Resonance...

Good luck, I like mine and I would recommend them. 
I have had the later FM's on my '97 C5 for 3 years with various iterations. With stock engine, ATI 7 psi only, 427 w shorty headers, 427 F1R LG LT's & 228 cam on 115 LSA.
Never had resonance, general noise level increases w/LT's and sooner opening exhaust cam, and bigger engine, but I live 1 block from police station and drive sensibly and they never even look at me.
At full song w/blown 427 the sound will scare the alimentary canal excretory eflux out of anyone not expecting such a cacophony!
I don't know the weight of them, but they are big and heavy, that's the one disadvantage!

Theres no better sound than a flow master. Classic muscle car or current, hollow sound is awsome and at WOT you will swear your running as close to streight exhaust as you can.And they do sound like a tin can because thats almost what they are! I used to two chambers on everything Iv owned and Im trying to figure out a way to install two two chambers for the C5s. NOTE If you like the exotic sports car sound you will not like them though!
