The muffler and resonator on my 1999 Dodge Ram2500 24valve cummins needs to be replaced. The garage said I would get better gas mileage, better performance, and less engine wear if I replaced the whole system from the manifold back with a true all 4" exhaust system. Apparently the original stock system which is still on the truck is not 4" all the way. $250 to replace the muffler and resonator and $1100 for the complete system. Is it worth it.
Thanks, Keith
