As requested by a few CL members here is a video I made a while back just for kicks. Sorry about the poor quality video, but I had to compress the nearly 1 gigabyte original clip down to 100MB for hosting.
Here it is for your viewing and listening pleasure. Enjoy! RMM Exhaust Comparison

 

it's actually kind of quiet and subtle... what kind of mufflers does RMM use.

 

i agree, quite quiet.

i looove the sound of stock exhaust sc's, they just sound so mean...i remember when i was in the search for one i got next to one at a light, bone stock, and when it took off...just sounds beautiful, KIND OF like the 350Z...just a great sound.

 

From what I understand they use their own mufflers. They don't look like any aftermarket mufflers I've seen. They are a bit longer, heavier and do seem to do a bit more "muffling" than the stock units. However, they sound deeper at idle and more aggresive at WOT. One of these days when I'm not lazy I might pull them off and bolt up the stock mufflers without the resonators and see if there is any difference.
