i would run dynomax.
awhile back i saw a test (i couldn't find it again, sorry) where they took a stock ls1 trans am and put every muffler available (borla, flowmaster, dynomax, etc.) on it one at a time and ran it down the 1/4 with the same conditions (same track, temp, etc).
the dynomax produced the fastest trap speed and elapsed time, only change being the mufflers. i'd therefore recommend dynomax.
