wkwanjr -> flowmaster muffler (7/11/2007 12:15:48 PM)

i got a '01 2500hd 2wd crew cab, short bed & 6.0l. i talked to someone at Flowmaster about which mufflef to use, they told me to use the big block 50 (3-chamber, dual in-dual-out), but i thinking about going with the 2-delta flow 40 (2-chamber, single in-single out). the 50 is pretty big, compared to the 40 , they said i would lose too much back pressure with the 2-40s, but the 50 (3-chamber) is quieter than the 40 (2-chamber). the volume of the 2-40s is less than the volume of the 50, but if the volume (2-40s) is less, how would there be less back pressure. i don' tunderstand!!!! if any one can help me out, i would appreciate it.
