Exhaust drone - Mac MMS Mufflers

[KKOSH]

Just bought these new for my 07 GT500 and they drone pretty bad up to 2100 rpm. Don't know what to do. I like the sound otherwise. I bought these because it seemed like they had good reviews. These replaced magnaflow muffler deletes that we're to loud/raspy for my tastes. The drone gives me a headache! Was thinking about the KR mufflers? Looks like I might be selling 2 pairs of mufflers. Is there any recommendations?

Put on some weld in resonators. This will help.

Wow I love my MMS's and I have Lt's. I love this setup.

The KR's sound really good. I had them w/ the stock headers initially and they had a nice deep rumble, I later added lt's and a high flow H pipe and they really sounded mean.

I just don't notice the drone, but I always have the windows down listening to the exhaust and blower and also the radio cranked up.

Go with KR's no drone. Want to kick it up a notch add a H pipe with KR's.

I'll second the motion on the KR/H pipe combination. I've run those two on my '09 for a few years now and have been very happy with it. Boss sidepipes have been the cherry on top.
