Magnaflow vs Gmmg
my car with just a magnaflow catback was louder than my friends Z28 with the gmmg catback. you wanna scare people w/o being obnoxiously loud, magnaflow is the way to go. i will find some other vids of my car, before the LTs and ory, if u havent already bought the gmmg
stock manifolds, stock catted y, magnaflow catback

I haven't heard the Magnaflow in person, but it sounded real nice on LS1sounds.
The stock catback was just too quiet IMO for this sort of car, and the GMMG isn't too loud, but is aggressive at the same time.
I was kind of surprised by how loud it is, IMO a lot louder than stock, but I like it, esp at WOT.
I would of liked to hear a selection in person before purchase, but living in the UK, hearing different combos on f-bodies is not easy, as these car were never sold here.
Anyhow, thanks for the advise, I'm off for some more WOT action!!

I was satisfied as hell with my GMMG on stock manifolds/cats ... it sounded beautiful and I was happyw ith it...
after my LT's/ORY... i can no longer say I am just satisfied and happy with it... I ******* love it, it puts a smile on my face every time I hit the gas, even when I have the stereo up loud... I've never been more impressed with a catback like I have with the GMMG. I can easilly say that if I get another F-Body for a toy or project or whatever, even a 3rdgen... GMMG is likely the only way I'll go
