Since the search button sucks now and isn't pulling up anything, and my dial up won't let me listen to ls1sounds.com....Who has the gmmg with longtubes? I've got the gmmg CB on the way and am considering QTP LT's w/cats. Living in CA I don't want to attract too much negative attention. Would adding LT's to my already heads/cam and gmmg be super loud? Would it be loudmouth and offroad pipe loud? Would it sound very raspy? I know this is pretty subjective, but any input will help. Thanks.

 

Nobody has longtubes with their GMMG?

 

I have just had the GMMG installed. I just got in on the GP for the Kooks LT's and Y pipe and am waiting for them to arrive. What I can tell you is rasp and drone are not words that I can associate with my GMMG CB. I expect the LT and Y pipe install to give me more of what I am experiencing now, which is a throaty mean sounding V8 growl

 

Yes, LTs will open up a bunch more sound, especially with heads/cam. I'd say yes, Loudmouth and ORY loud unless you get a catted Y.

 

Well I do plan on using cats, so hopefully it won't be too much of a cop magnet. I'd love the mean, throaty sound I assume it will give, I just don't want to be alerting every cop in a 2 mile radius driving around.

 

I have GMMG with Kooks LT's, catted Y and stock cam and it sounds great. At WOT, it is louder than my friend's LT1 355 that has a good size cam, Hooker LT's, ORY, and 4" Mufflex. I have heard GMMG with an ORY and it is really loud. I def. put cat's on to keep the noise down.

 

I've Kooks lts through the catted y and back to the gmmg. It's quite loud and agressive with the stock cam and it's even more so with the MS3 installed. It's an enjoyable loud though, it never gets annoying to me. Too bad I'm selling the gmmg and catted y for the sake of power gains .

 

Thanks for the response. Sounds like it's gonna be pretty loud even with cats. Is there any rasp?

 

You can hear my car from pretty far away when it's at wot, there's no doubt about that. I've never expierienced any rasp, I'm pretty sure the cats get rid of all of it.

 

GMMG + LT's = loud, no matter how you slice it. But its a very clean sound, especially with cats. I think it will draw attention, but not negative (well, any noise to some cops will get their attention)

It is very subjective, but I think if you get cats, a cammed car w/ lt's and gmmg will make you smile

 

I agree.

 

here you go

You can decide this is with high fow cats and man it sounds awesome.

 

I gotta say that I just installed Kooks LT's w/cats and a GMMG catback and I get considerable rasp around 2-3k rpm under moderate to heavy throttle. Other than that, the setup sounds great. I'm thinking the reason I get the rasp is because I'm using Kooks' new metallic cats, which are almost like having no cats since they flow so well.

Do you have a soundclip?

 

Why dont you just mate your current y-pipe/cats up to the headers when they get there? I have the magnaflow cats on my car now with 3" duals. They made the car incredibly quieter.

This option is much cheaper and will flow + reduce the noise great. The flowmaster merge is also a very nice piece.

Any reason you are looking to get rid of it?

 

That is an option. It kind of depends on what LT's I get and where I have it done. I'm not really looking at getting rid of the y-pipe/flowmaster merge though....I'm just trying to get an idea of how loud longtubes will make my gmmg.

 

No, sorry I don't. If I had the equipment to make you one, I would.
