FWIW you can have one made. I forget the exact model of muffler that comes on the team moon but that info is easily available on this forum. Someone was offering essentially a center exit team moom dual exhaust several years ago. Also, TM duals are loud AF!!
It can be loud if you have an aftermarket downpipe.
On the whole however it not so loud at idle and just driving around normally. Almost like those factory exhausts that have a valve to regulate the sound because when you get on it its a good glorious loud.
@FormInFunction - I had called mazcare in GA last week and they confirmed they can make one but the timeline was closer to ~1-2 months out. Plus price to ship across the country is bonkers these days.
You only need to order the muffler, a quality exhaust shop can do the rest. Not exactly cheap but neither were these things new...free shipping on Amazon also helps put that part of the cost towards the local fabrication.
