This may sound like a stupid question ( I seem to excel at stupid questions lately ) But I recently had my exhaust swapped out for a new Flowmaster axle-back system, but when i picked it up from the exhaust shop, it sounded raspy, kind of hollow. but by the time i got home and ever since it has changed it's tone a little bit to slightly more low, deeper kind of exhaust sound. My question is do exhaust systems change their tone after being in use for awhile ?
A muffler with packing can change over time but a Flowmaster is not a packed muffler. What I think you may have heard is a cold start vs after wit warms up. The engine idle speed and tune for cold start change the sound a bit.
Flow master mufflers have shields in deltas to deflect and tune the sound. The sound should not change with this. Now some flow through mufflers with packing in them to dampen the sound can change as the packing burns out a bit.

I had a Corsa Sport/Touring system on my lat C5, a coupe, but I bought this 'Flowmaster' axle-back system last year, it was cheap $1000.00 but I only got around to installing it this month. The car is new " To Me " so i'm just now getting to find all the little things that get your attention. It's not too loud and I bought it because it was advertised as being acceptable out on the highway ( I plan on some long road trips soon ) !
I've run just the C5 specific Flowmaster mufflers (must cut stock mufflers off, and reuse OEM over the axle pipes) since 2004. Real nice sound, though after 100 miles of freeway driving, they can drone. Ive sandblasted mine twice, and repainted flat black with VHT paint. I love mine. But they were $250 for EACH MUFFLER in 2004!!!
Yeah, I'm not too crazy about the 2 outlet pipes but I couldn't pass on the 1K price tag, I guess after the next 1k miles I'll have a better idea, but I saved the stock pipes just in case.

I kinda like them. Mine are pushed together on each side. Like a double D, one backwards, with both flat sides of the D butting up against each other. Like that on both sides. I noticed that the 2 outlet pipes on each muffler are at least 1/8"-3/16" larger diameter than the stock ones. May not matter on a stock engine, IDK. But with a large displacement/modded/FI engine, it might...
Exhaust systems ?
