Re: GMMG I have NO drone whatsoever on my 2002 Z28 with the GMMG. But since this exhaust isn't exactly quiet, your car will be noticeably louder in the interior. Trust me, all loud exhaust will cause some kind of vibrations inside your car. Some are just worse than others.

Re: GMMG Congrats on the new purchase <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
I have had my GMMG on for about a year and a half and I have no drone on the highway. Basically the only time I get drone on the highway is when I'm above the posted speed limit <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
The one thing that you will want to do while the old exhaust is out and before you put the new one in is to get some really thick rubber hose and cut little pieces and wedge it between the gas tank and the heat shield. That was the only rattle/vibration I had when I put mine in.
Enjoy and let us know what you think.

Re: GMMG I don't have any drone inside my car. In 5th gear at about 2500 RPMS's i gets kinda loud but it settles down very easily. You'll love this exhaust. For me it was exactly what I was looking for. A loud and deep exhaust note with no interior resonance/drone.

Re: GMMG Dynamat is a car audio thing - it is a damping material to stop vibrations and road noise.
Dynamouth is the exhaust that is the same as a loudmouth only replacing the resonator with the dynomax muffler.
Don't know which you were looking for, but I figured it was the exhaust.
