Friends Coach Travel Supreme 2007, 500HP Cummings Engine with rusted Muffler. Any suggestions where to purchase one... Living in Lafayette La. Thanks for your help DANO !
2007 was first year for Cummins using the Diesel Particulate Filter (DPF) which is part of the muffler assembly. Maybe the coach has 2006 engine which would have a standard muffler.
If it is the DPF muffler, a replacement is about $2,600 - $3,000.
