Default GMMG Exhaust!?

I will have a 02 Z28 in June. It already has Lontubes, ORY, and catback but i wouldnt mind switching the magnaflows for GMMG! I have heard them a few times. Please post videos of LS1's with LT's, ORY, & GMMG catback!?

there are plenty of vids. but having the ORY on the GMMG is gonna be super loud and raspy. better off putting some high flow cats in.

Oh yeah, TA or camaro will be the same exhaust sound.
I just typed in "gmmg" and it found quite a few.
I really don't think listening to them through a video is nearly the same as in person of course.
Some people dont specify their whole exhaust setup also which sucks.

Just found out my buddy has a GMMG exhaust and he thinks it's too quiet with his setup. So I may get a good deal on it. I have the same setup. Hooker ceramic coated longtube headers with a 3" Hooker off road Y pipe into magnaflow catback with no cats. Magnaflow just isn't loud enough for me neither

Lucky SOB!!! When i saw the car I bought/downpayment, the guy had LT's, ORY, and a catback without the magnaflow muffler on it, so it was extremely loud!!! Havent heard it with the magnaflow.

Idk how much he payed for it but it was used b4 him. He just slapped it up to his car and ran around with it only for maybe an hour or so and decided it was not Loud enough. I thought he was crazy considering the cam he has. Like I said, I don't know how much he got it for but hopefully he can cut me a good deal. One of the hanger plates got broken so he is waiting on that piece to come in. If not I'm sure I can cut some metal and weld it to the bracket area. I would love a GMMG. It would make my car even more like a dick harrel.

How does your magnaflow sound with the LT's and ORY? Raspy like the GMMG at all? I really like that sound.

Magnaflow doesn't really have a loud sound with lt's and ory. It's a low quiet deep sound and a little raspy, but that's bc of no cats. What I like about borla, corsa, and GMMG is the loud and cackly sound. How it has that Gnarly "Im gonna rip into your ***" sound! GRR! Ha ha.

And twitch, the reason I love my magnaflow is bc it's quiet for my daughter. But a full exhaust like borla or GMMG is that it's quite louder but yet it's all behind you and not droning under the car.

I just noticed the mods in your sig. I am willing to bet that youragnaflow does sound pretty good. I'm willing to bet also that if I get a cam and upgrade my intake and everything that myagnaflow will sound pretty darn good too

GMMG is LOUD with long tubes and an ORY. Guy I know has a head/cam car with kook and gmmg...it is way to loud for my taste.

When I was 17 and first got into f-bodies all I wanted was loud...I could care less how it sounded as long as it was loud. Now I am 25 and drive a lot so I will take quiet please.
