So, I hate to make another GMMG thread, but I can't find any recent enough ones that would be worth bumping. I have tried calling GMMG and their number doesn't work, and from the searching I've done, I can't find anywhere to get them except Vengeance racing?.. I go to their website, and it says it has to be ordered directly through ls1tech, so here I am. Can anyone help me out with this? Thanks.

It's not, and never was, made by GMMG. It's made by a company named Mad Hammer.

You can either get them directly from them, or go to byunspeed.com

Thanks, so it's the exact same exhaust that is listed on the GMMG website?

I will probably be ordering this asap. Is there any reason it's a little bit cheaper? Anyone have some suggestions for tips? I don't know if I'm entirely cracked on the ovals.

If not look for stainless steal chambered exhausts. I heard they were very similar, if not the same, as GMMGs.

Stainless works exhaust is a 3.5 to a 3 inch exhaust catback with three power sticks it is better than the regular gmmg. The gmmg style is 3 to a 2.5 inch exhaust with two power sticks. If you have long tubes you will have rasp with this set up. If you go stainless works it costs more but over all is a better cat back

Yes, I've looked at the Stainless works, and I'm just not sure if I could afford that one, I've been looking at cat-backs for a pretty long time now, and I haven't heard anything like the GMMG. I'm kind of set on this exhaust, and I think I've made up my mind. I do have headers, so I am a little concerned about a fix-it ticket, Is this exhaust going to be a big red flag on my car? I'm looking for loud, but not if I can't get away with it.

Thanks for the responses.

The one thing. It sounds great at idle. But at wot it is idk. I'm going tsp true duals for 500 instead of my gmmg and y pipe

SoCaZ28

Can you hear your car from real far? I do have people tell me they can hear me coming to work already, so I'm not sure if a louder exhaust is a good idea on my part. I think I would be ok though as long as I'm not beating *** everywhere with it. Thoughts? (BTW It is for a DD)

mine sounds pretty badass at WOT. Although i agree idle sounds even better. But then again i have an lt1. GMMG, gutted cats, and stock manifolds for now
Ive heard GMMGs loose their magic once headers go in, others say it sounds better. I guess i have to wait and find out. If it sounds too raspy or sorry, then true headers it is.

I have been told it's extremely loud when I'm driving. I am used to it but the neighbors notice it a block away lol

Please save yourselves the search headache and read this thread. For those that complain of rasp and all around "shitty-ness" with LT's and no cats....

Absolutely NO reason why you can't run LT's and an ORY and still sound great.

Where in ca are you? I have a real gmmg sitting in my hallway waiting to be put on.

If you get the Mad Hammer exhaust and want the oval tips, they are listed in the link below. They are pretty much exactly like the GMMG oval tips. I'm not sure if they made them for GMMG or not?

Thanks, checked out your vids, sounds real good. Will try to be running a similar set up depending on how killer the rasp is.

Thanks, I'm looking at those, but are there any more reasonably priced high polished tips? Right now I got the stock box tips. I like the square look more than oval I think. I saw the high polished square tips somewhere online before, but I can't remember where and since then I haven't found them.
