Due to a lucky find on E-Bay I was able to source a brand new set of SLP PowerFlo mufflers, and due to a really great member here I was also able to get the beautiful big cast aluminum tip - brand new, still in the box. I'm still looking for a set of correct over-axle pipes, but for now it's connected to the (modified) stock pipes. With the FRC and a thick divider for the trunk interior noise is minimal. It does sound great with the windows down! IT's not a screaming banshee, but it sure has an aggressive snarl. When I have more time I'll get a better, longer video with some in-car time as well.
I had this exhaust on my old C5 and loved it, loved how the tips filled in the back opening and the sound was great as well. Got a lot of compliments. I painted the center cross section between the two openings with high heat black paint to hide that cross piece a little more. Really made the tips pop especially with the painted black rear as well.
Here is the only pic I have after all was finished

YES, I added some sound deadener not sound absorber but didn't do what some think it would. Looking at another product that absorbs sound you can just cut it & lay it in place no stick, I want to do a sound level meter test to see how it does.
Very little. More cabin/exhaust noise than done. It might be worse with more mods, I don't know.
I think because mine is an FRC with a divider panel there is less noise/drone. I had the same system on my 99 coupe in 2011 and I do remember that the drone was more noticable.

Could be. SLP is not known to be drone free or quiet.
I have noticed the drone is extreme, more when cold at RPM's below 2,000, once it warms up not as noticeable , also in 6th gear at 70, if you had to road trip not what gear or speed I would be driving for extended periods. Also much better with windows open.

Did you get those from me? I sold a set a couple of years back on here, but I don't remember to who. The shape didn't fit up with my diffuser so I ended up with this:
