I also have Emgo short reverse cones and like them. I know they aren't the best but for the price they are hard to beat. I got mine off E-Bay, but you can get them just about anywhere. I recently repacked them and they sound great. They are very loud and I wear ear plugs most of the time. Unlike some mufflers that seem quiet until you get on the throttle these are loud even at idle.
Here they are new chrome.
And with some black engine paint to match ceramic coated headers.
One other thing I did was drill out the end of the baffle. The pictures are from the end with the cones removed.
