I installed one on my Rebel about a month ago and must say, this exhaust system is awesome!!  It seems like everyone compliments me on it.
Excellent fit and finish, and I mean excellent!  The final adjustments were great for a perfectionist like me...you can really get it lined up perfectly.  The appearance is awesome!  The sound is exactly what I wanted in regard to volume and tone.  The install was easy--minus getting the rubber hangers off the stock muffler lol.  Buy the tool if you don't want to cuss once or twice!
The only downfall, and I knew something seemed wrong...the exhaust clamps called for 60 or 65ft-lbs if I recall.  The 'ball joint' for the final tip alignment is not 65ft-lbs.  Maybe I missed it in the instruction booklet, but one of my ball joint clamps snapped when trying to torque it.  'Funny' that I was telling my friend the whole time 'This bolt/clamp cannot be 65ft-lbs like the others.'  Only to have him reply 'that's what it said'  so I kept going, brought it up again, kept going, and snap went the bolt.  BOOM tip hit the ground.  I almost cried, stared at it for a bit, but luckily that black chrome finish is well adhered.  I got some minor dings and scratches, and had to reuse the stock clamp on one side, but it worked out.
