Default gmmg with headers

How does it sound? Any sound/video clips we be great? I will probably run it with cats so how much different will it sound with running cats as compared to running an off road y pipe? Any other comments on this set up? Anyone think it is too loud, gmmg with headers and cats?

It will sound great! I heard a friends car with FLPs and the GMMG catback and it sounds perfect. If I have the oppurtnunity I will get some sound/video clips.

Please post some sound-clips <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I have FLPs with FlowMaster AT catback and the sound it produces is really not what I'm after. I was thinking about going with Borla, but I have also considered GMMG.

Please post--Thanks <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

I get compliments almost every time i drive my TA. I only drive it on the weekend and it sure does put a BIG grin on my face when i fire her up!

My daily driver is a 5.0 'stang so i get to sound good during the week but there is just something about the GMMG/LT combo that i love! <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

And you know the GMMG makes no power how? <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

The GMMG sounds good and makes hp too just like any other aftermarket exhaust. People (myself included) have dynoed the GMMG against other exhausts and have made the samp hp or alittle bit more.

Borla does sound good in a tractor sort of way though. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

The GMMG does have more of a tuned sound than Borla and the Loudmouth and will match the perfomance, but I think True Duals would be better than any of the catbacks available for the f-body.

The GMMG like just about every other aftermarket LS1 cat-back(except Flowmaster) available will flow just as good as the Borla on your average LS1. There have been many dyno's(including Cobra Eater's) that have proven this. I switched from the Borla & LM to a GMMG and lost NO power. Just because you have a Borla doesn't mean your gonna run away from a GMMG car.

The GMMG exhaust is just as good as all the others. The only reason this myth that it sucks exists is cuz it used to have 2 mufflers, not it only has one. The two muffler thing was a bad design, but they have since improved it and now it is one of the better exhaust choices.

I swapped out my SLP dual/dual (stock with my firehawk) and lost no power whatsoever, I actually gained like 1hp but my car had a bit more miles on it.

Blue Fire,

Not to start any flaming but your statement is a bunch of <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />

I have the GMMG with FLPs and the ORP setup. It sounds great but is pretty loud.

I have not dynoed against other exhausts but I pulled 421rwhp with this exhaust on my heads/cam car. And all I heard was how my catback was going to hold me back in a setup anywhere near 400rwhp. All this cam from folks with no experience with this exhaust.

GMMG Rocks <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

The GMMG still has two mufflers! It used to have three, but they got rid of that one on the intermediate pipe after Dec.2000(2nd gen to third gen GMMG exhaust now). <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
