Side exit/AAR style exhaust

I'm looking at going this route soon and am wondering, for those who have or had it, what mufflers you ran? I am going 3 inch. Was looking at dynomax race bullets, ultra flos, or possibly black widows. Open to suggestions as well except Flowmaster. I like the sound of the ultras but I don't know how loud they are.
AAR exhaust mufflers had the inlet and outlet on the forward facing end of the muffler. The reason they did that is because some state's laws required the exhaust to go at least as far as the rear axle centerline.
When I bought my AAR in 70 the mufflers and tips were in boxes in the trunk. There was a printed service bulletin in with them explaining that the installer needed to consult and conform with local laws when installing them. I think that some states even required the exhaust to exit the rear of the vehicle.
