GMMG CAT BACK Decibal level??

[CAMAROZ28AQUINO]

i want to purchase a gmmg catback system on my bone stock z28. I will have the stock manifolds,and y pipe, just the cat back will be changed. How many more decibels approximatley will this be over stock at idle and WOT. i love the sound of gmmg but i want the noise level to be as near as stock as possible? Any suggestions?

its noticeably louder

ull never have this exhaust close to stock

keeping the manifolds willl help tho

u dont really hear it during part throttle or cruising, but once u open up it will be much louder than stock and sounds sooo much better

headers will change everything and its soo much better

if ur looking to not have a loud car just stay stock and do no upgrades

What year is your Z28?

It sounds different on the LT1 cars than it does on the LS1's, but you didn't tell us which one you have.

Why not add a "signature" with the basic info about your car.... year, tranny type, major mods, etc. That will increase your chances of getting accurate responses.

Being that you have a pretty much stock exaust, its not going to be that bad. But if and when you get headers and decide not to have a cat it gets real loud. Most people that I know who have them put a resonator in the I-pipe to cut down on the drone at part throttle. But other than that its pretty aswome sounding system.

The z28 is a 1998, LS1 equipped, so do you guys think gmmg is worth it, anyone know if they ship to Canada??

I love mine not loud when driving around easy, but just step on the gas and its hard not to step on the gas GMMG

I dont think it's worth it. The cost is just crazy for a simple exhaust. That's my opinion.

[jsetzer]

Sound good? Yes
Too much money? Yes

[black02z28]

How about flow wise is it a high flowing exhaust??

[rlax31]

i've seen people say it dynos 3 less hp then open cutout, so yes

Wouldn't trade mine for another

I think it is worth it.

I was told it's about $225 to ship it to Canada by UPS ground. UPS will add another $60 in charges on top of that. It's free shipping if you live in the US. I'd recommend shipping it to a friend south of the border.

Assuming you ship it to your door, you're looking at about $1200 for the standard setup and $1400 for the oval tips setup.

Is their any other systems out their that are cheaper and sound close to gmmg with no rasp and isnt as loud??

That 3hp couldve been caused by 50 million things.


Anyways I plan on making my own version. There is no way I would pay what theyre asking. It's insane.

[kick Z tail out]

It's never gonna be anywhere near stock sound levels...


Here's a video I made for people that were sending me PMs wanting to hear the car in various situations:
