for the exhaust, the duramax 07 emissons guys are cutting out the dpf/cat and setting sensors aside unmounted and putting in a strait pipe. for wheels/tires everyone has there own opinion. i'm not sure what to refer you for on the 08s. but for tires I'm partial to BF Goodrich all terrains 35x12.50 on a 4.5" donahoe racing lift.
04 Silverado 2500HD LB7/Allison, EFI live by duramaxtuner.com with DSP5, 4" MBRP turbo back straight pipe, polished 5" tip, 5% tint, riding on 285 fierce attitudes, many more mods....
