I need to know if there is a great performance difference or Noise difference between these 4 types of exhaust...

1) Eisenmann Rear Muffler Exhaust (Axle Back) (Sport)

2) Eisenmann Rear Muffler Exhaust (Axle Back) (Race)
..........Same URL as Exhaust 1

3) Meisterschaft SUS GT Racing Performance Exhaust (Cat-Back) (Sport)

4) Meisterschaft SUS Touring High Performance Exhaust

I just Need like a rank order of performance (the first = best, last = worst)
..................and a rank order of noise (the first = loudest, last = quietest)

ex. perf : 2,3,1,4
.....noise: 1,3,2,4 .......... <- My Predictions
