Have 4" TB Magnaflow SS exhaust: Want to go with a smaller muffler. What options?

Hey all, just picked up a 2000 QCSB with a 4" stainless turboback Magnaflow Exhaust. I want more sound out of it. It has a 30" muffler on it for now. I am basically wondering what is out there for more sound minus just running a straightpipe. If I have to I will, but would prefer not to as I leave the house at 5:30am and I do not want to wake the neighbors up. Thanks in advance guys.



2000 QCSB - Suncoast triple disk, Shift kit, Isspro gauges, 4" SS TB exhaust, Holley Blue, Silencer ring MIA, Banks(soon to be replaced with Edge Comp)
1988 K5 Blazer - 4" lift, 33's swampers, sm-465, 350 tbi

Can you turn your muffler around and flow it backwards? I don't know what the Magnaflow muffler looks like inside, but on some, turning the muffler around reduces the restriction. You will probably have to get some flaring work done and extra 4" pipe to do this.

I've run straight pipe and a muffler. My preference is to go with the muffler because it reduces the reverberation of the sound, i.e. eliminates the "drone" when you are cruising.
