2003-2006 Chevy Duramax 2500-3500 fs19-mods

Description:

(THIS IS NOT MY MOD IT HAS ONLY BEEN SLIGHTLY TWEAKED) This is a slightly modded version of Machines Modding 03 to 06 Duramax, The original sound on it was a bit odd and twangy and had a very high picthed whistle at high rpm so I change it to a LBZ straight pipe 4 inch tip sound file. Go check Machines Modding out on Facebook He makes some pretty good mods
