Default exhaust question

Which exhaust is the better one to go with (Pro Flow, Magnaflow, MBRP, Banks, etc....) If I left one out just list it.

I have a 03' chevy duramax crew cab 4x4 w/ the short bed. I have these mods the banks six-gun tuner & the speedloader, banks ram-air.

Thinking about going with 4" down pipe from turbo and 5" straight pipe with a 6" tip. Dont really know much but I know there is alot of different brands out there.

Which do you recommend?

I would go with the MBRP system, they have proven to be the best to us.
