I have a Diamond Eye 4" straight pipe dual exhaust w/ 6" tips for an 04.5-07 Dodge 5.9 Cummins. Had the exhaust on a 2006 for about a year. Had to take it off because it was WAY to loud for my taste. One of the loudest exhaust systems i have ever heard, so if you like loud, this is it. $400 OBO. P.M. me for details, Thanks.
