Magnaflow vs Gmmg
I have listened to www.ls1sounds.com, and the Magnaflow and Gmmg catbacks sound the same to me.
The catback is a replacement on a stock system on a 01 ws6.
1. Is Gmmg too loud for anyone? (At normal cruising).
2. Is there any rasp/drone with Gmmg?
3. Which has the deepest rumble?
4. Will the magnaflow scare people at launch?
5. And most importantly, is Gmmg worth the extra $$$ ?
I can not hear these catbacks in person, so any input is much appreciated.

I've had both on my car. Some of these answers will depend on whether or not you have longtubes/cats.
1. It's not loud in the cabin, but is pretty loud outside(especially w/longtubes).
2. VERY MINIMAL drone, almost none with stock manifolds and cats. It won't give you a headache like the LM will.
3. The Magnaflow is real deep, but smooth like butter and not throaty in the least. The Magnaflow is a decent sounding muffler though. It just didn't have the throaty sound I was after. The GMMG is deep, throaty and sounds grumpy like a real muscle car should! The Magnaflow won't scare many people, but you can definately scare people with the GMMG.....I have lol! With heads/cam, longtubes and the GMMG, I've had people jump several times on start up! Expect some compliments when you put a GMMG on.
4. Believe it or not, the GMMG IS worth the extra $$! I had a hard time justifying it myself, but it does sound like a $700 exhaust. It's hard to tell from listening to soundclips on the computer, but the Magnflow and GMMG sound VERY different in person.

IMO, GMMG hand down.
The GMMG sounds like it is what I am after.
Worth the extra? Most of you seem to think so.
I was going with Magnaflow, but read alot about it being too quiet for some.
I want louder, not abnoxious loud, but loud enough to scare off most of the local ricefield. (A LS1 over here is nearly as rare as rocking horse *****).
One WS6 with GMMG comming up!!
Will post back with my thoughts on the new set up.
