Performance wise, it sure as hell doesn't seem to be.
But sound wise, it is one of the best on the market, IMO of course.
Unfortunately, that is not a sacrifice most of us are willing to make. SW exhausts are not getting the best rap lately. Race Proven Motorsports posted a vid last December of a CTS-V losing 100+rwhp on the dyno using a SW Retro catback (the turbo muffler style). They did back to back dyno runs showing the loss/gains.
The response they got from SW is very interesting to say the least...
