Topic: Anyone put a cat-back on a 5.3 with active fuel management?

The title pretty much says it all.  I've read a few reports of a twangy sound when it shifts into V-4 mode.  Some say yes, some say no, others say it depends on the system.

I would like some real world opinions from actual owners.  To be honest, the truck is so quiet on the highway, I think it would take an extremely loud exhaust system to even be able to hear it at all inside the cab while cruising at highway speed (the only time it shifts into V-4 mode).

(putting on my flame suit for asking this question about my Silvy on an AV board but I trust you guys.)

With the Corsa system all I can see is the v4-v8 mode on the DIC. Can't hear a change in the exhust

Thanks Glenn.  That's what I really suspected with any quality system but some say different on the performance websites.  The funny thing is that those people usually don't have anything newer than a 2002 listed in their sig line.  I figured it was mostly people that had no idea from real world experience that were running their mouths.

I'm not turning this truck into a hot rod like the AV but I would like it to sound like a V8 when I'm sitting at a stop light or accelerating.  Right now, I have to look at the tach to see if it's running.
