Corsa Extreme question

[fortrl]

I know all the talk of Corsa Extreme and sport cat back has been run in the ground but for anyone who might know the answer to this I would appreciate it because it is a sizable investment for me. If anyone has heard the Roush off-road extreme cat back for the S-197 Mustangs ( no muffler just resonators), I was wondering which of the Corsa Extreme or Corsa Sport fatback is closer as far as loudness goes. I know the tones will be totally different but under full power. If what I'm reading from everyone is right so far, there is little difference in the Extreme and Sport while not under WOT. I had the Roush system on two different S-197 cars so I was hoping someone would know which it compares to most.
Thanks in advance.

I can tell you this first hand. At 50 feet away Corsa Extreme cold start is 68 db. I know because I checked because of bitching neighbor.

I've personally installed about 10 Roush extreme catbacks, the Corsa extreme is roughly the same, Sports are a little quieter.
