I'm gonna be buying a GMMG catback soon but I'm still kinda hesitant about a few things since I haven't heard it in person. How loud is it compared to stock? To flowmasters (which I unfortunately got with my car)? Do they really make the stock cam lobe more noticable?

 

I had Flowmaster on my old car and then GMMG and the GMMG sounded a million times better. Best sounding exhaust I've ever heard especially with Long Tubes and No Cats, you will love it, get it!

 

The flow masters suck so bad, its barely louder then stock and pops alot on deceleration. Do they make the stock cam lobe noticable?

 

Stock cams don't lope though Well, maybe if you turn the idle WAY down.

 

not really but the idle sounds way better

 

I put gmmg on from stock it sounded AMAZING! You will like it!

I just put long tubes in with my gmmg no cats, I waiting for a part to arrive on friday and than i can start it to hear it. I am very interested on how it will sound

 

You're right, probably one of the better investments I made for the car and sounds awsom! Especially at WOT. GET IT!!

 

Just buy it, you won't regret it. Here's a clip of my car with the GMMG exhaust, just before getting my car tunned.

Just buy it! You will love it and you will not look back.

Go to my fquick.com page, I have a video there of my car idling. Best sounding exhaust period.

 

GMMG sounds great but I think it sounds better w/ cats. Has a more deeper tone to it but that just might be on big cube engines.

 

dude there is no comparison

listen to these:

flowmaster - GMMG

Also keep in mind, the flowmaster car has headers and cam and the GMMG is stock, and it still sounds better.

 

+1 Magnaflow

If I could do it over again, I'd prolly go with GMMG. It sounds better than magnaflow. For the money, I think magnaflow is great.

 

I have Flowmaster right now(came with the car when i bought it) and it annoys the crap out of me. I like GMMG bot gawd is it expensive! I am thinking Hooker or Dynomax, both sound good to me and are not going to break my savings account.

 

Believe me and the rest of us, it is worth every penny

First car: 383 LT4 Car, Borla with no plates
Second car: 355 Cam Car, no heads, LT's no Cats, Custom Exhaust with one Bullet (similar to a LM2)
Third car (mine): 350 Cam Car, no heads, LT's no Cats, GMMG
Fourth car: Stock LS1, LM1

I definitely recommend the GMMG or even Stainless Works Chambered Cat-Back

 

I have been considering changing out my Borla for a GMMG but have been hesitant. I wonder if I would miss the Borla. I've had it on since a week after I bought the car. I dunno.

 

If you do one day get a GMMG catback I'll buy the Borla off ya

 

I am going GMMG as my final answer in the future as well.

 

THAT GMMG clip is my car!!!!!!!!!!!! I think Im the only one on the net that had a gmmg clip on an lt1 with stock manis and cat

 

GMMG sounds good.

Another option is the B&B... it actually flows very well, has no drone/rasp with an ORY, is very deep, and has the best tips on the planet. Cost is a little more, though.
