Anyone know the cost to retrofit a DPF and EGR onto a 5-8 year old Cascadia or T660 that didnt come with one???? Also has anyone spent the money to add commercial soundproofing to a tractor cab?? please elaborate..
if you have a Cascadia or a 660 without an egr and dpf someone took them off. 2008 was the first year for both, egr started in'04 and dpf started '08.
