I've ran all three of these can's on my fusion and I would have to say slp was the best. It wasn't too loud, didn't lose too much top end and the overall finish and product was good. Next would be the Super Q which I'm running right now. Lost some top end power, but I like the sound, It's louder than stock but not too obnoxious. Just right for me. The ceramic coating looks great under the hood and is really light weight. The worst of the three would be MBRP. Other than this can is insanely loud, it is light weight too but, the finish was horrible and one of the welds broke at the top. It started to rust faster than the other two and put off much more heat which burned my exhaust insulation on the body of the sled. Definetly choose between slp or the super q.
