Exhaust---ED

[H2 OHHH!]

Is it just me or is modifying an H2 an obsession? I've read some previous threads about exhaust systems and some are pretty old. Want some new advice on a muffler/exhaust system. I have an 07 Escalade that sounds meaner than my 07 H2 and they both have stock exhausts. Want something that sounds meaty but not waking the neighbors when I leave the house @ 5:00am. I checked out Corsa's website and listened to the audio file of the H2exhaust and it sounds sweet! Any thoughts on Flowmaster, Xtremeflow? Thanks and if this thread is "EXHAUSTING" to some of you old timers I apologize. Everything I have done so far to my truck as been a result of this forum so thanks to all for the wonderful advice.
