Fiddling about on my computer today, I found a pretty good comparison video which shows a back-to-back Dyno run on my Blue Spider.
The car was sick when these were done, due to a bad electrical connection on the starter solenoid causing the Fuel pump to slow and the resulting low fuel pressure.
Its a pretty valid sound bite, as its the same car, same camera, and same place.

Run One is with a stock system with a Aftermarket replacement single Ansa Tailpipe.

Run Two is with the Magnaflow System fitted. The misfire was worse here, but the difference in sound is clear!.

Note he stopped at about 4500rpm... it gets a WHOLE lot nicer at 5k+

I will be posting a better video soon, now I know how to do it, but until then I hope this helps!
