I owned that LT1 Formula after my 98, so it was from 2001 to 2004 that I had it, and I think the Loudmouth was out, but the one I had was the 2OTL system.
Really?? I've had the 2OTL system on my car for the past 12 years and I've NEVER noticed ANY drone at ANY speed/rev range. Did you have long tubes on it, or no cats?
The only thing I have noticed as the muffler packing has worn is a 'revisionary' type of pop/loud burble on sudden accelerator back off after WOT in a lower gear.

Even if they did, it is also only 409 stainless, as is SuperSprint, and Remus as well, I believe.
VERY FEW use 304 eclusively throughout the WHOLE system; Borla, Corsa, Billy Boat, and maybe a few others.

I'm getting rode on M5board for not wanting to do straight pipes, LOL!
^^^Do they ALL open track/HPDE/Time Attack their Ms???
It is such a luxury/performance car, I too would not want that sort of harsh/raspy noise output (and drone) from it!!

Well, I have one guy saying he got Borla and that it is quiet, but the quality is superb. Then the next guy saying NEITHER!! GET STRAIGHT PIPES! LOL!

Nope, everything was stock, but that car was automatic with the 3.23 gears, so I'd be revving a lot higher on the highway than your car with the 6 speed.

I think the guys who ran an M5 in the Gumball a few years ago had a Borla on it.

Yeah, my buddy's stainless Magnaflow turbo-back exhaust that was on the Dodge 2500 Cummins he bought used has a fair bit of visible rust on the muffler. It was loud and drony, and didn't sound very good. He cut it out and installed a Donaldson truck/tractor muffler that sounds way better and is also more pleasant on the highway. It's 5" ID like the rest of the exhaust so it likely improved flow as well. We were surprised to find that the Magnaflow actually had a 4" ID through the muffler only.
Based on this experience, I'd go with something other than Magnaflow.

It does!
Now that sounds dirty!
That's the closest I've ever heard a BMW sounding like a Mustang.
I love Borla, but that Corsa system totally gets my vote now!!
Love it!

Corsa is unique in my experience in that there is very little noise in the cabin, and the exhaust is nearly stock sounding at smaller throttle openings.
But when you punch it it SCREAMS! So will your wallet.
Sorry, but IMO it's ridiculous to take a high end car like that sweet M5 and make it LOUD. The power gained from an exhaust is very small, and it typically moves the torque up higher in the rev range.
But it is your car and I respect your right to mod it any way you want.

But you just said it is only loud when you are on it!
I like louder exhaust. Not obscene, but loud enough. Just my "thing". Call it a carry-over from being a Mustang guy

It's not a problem. I may have more than one vehicle that could qualify as loud.
As I said, it's your car. You own it, and thus you get to do whatever you want to it.
At least Corsa is one of the best out there.

For most of the other cars I've ever dealt with the Corsa systems (along with the Billy Boat, and Bassani stuff) are way more coin than the Borla stuff.
But, they are also VERY WELL crafted, fully 304 systems which sound GREAT!!
For some reason though, they have a rep for being one of the heaviest systems out there (if that means anything to you), at least in C5/C6 Vette circles.
Maybe they use a thicker walled 304 than everyone else, or their tips are a MUCH heavier gauge??

This system is something like 15lbs lighter than the stocker
