exhaust question

[grease99]

ok, just got a new duramax 1 ton yesterday. im lookin for exhaust. I dont really know what kinda aftermarket there is for the Duramax as the only diesels i have messed with were cummins. i was thinking about the Banks, MagnaFlow, or MBRP. Wondering if anyone out there is running any of these and how they sound and perform. Also if anyone recommends anything else. im not doin much to this one, just baggin, 24.5" Alcoa's w/ low pro tires, exhaust, chip and intake. thanks for any help.
