Still very happy! It does have a small amount of resonance/drone around 1800-2000 rpm or so. It's honestly not bad and I'm either slow enough in town or fast enough on the highway that I don't see much time in that rpm range. Towing roughly 7k lbs it wasn't obnoxious either, but I haven't done any long distance towing. Sometimes I wish I had done a 3" system for a deeper sound, but that's too much pipe for this motor and I'd rather not have the drop in low end torque.
I'd 100% do it again and I still like how the mufflers sound, doesn't sound like every other hemi in my area. If you're not anal retentive like me you could save some money by having a shop do standard bends instead of pie cutting and welding pre bent mandrel pieces and if you're not in a rust prone area you could also save by not going stainless.
I do think if you did the MPI system you'd probably be happy with it, but I really like the fact that I was able to fully spec everything exactly how I wanted from what kind of cross over, material, muffler choice, exit angle, etc. and actually be a true dual system. The cost was similar to a bolt on dual exit catback.
