I'm new to the message board, new to Dodge, and new to Diesel. Just
bought a 1996 3500 Dually with the cummings. I will be doing alot of
towing with it (13,000 to 15,000 pounds). Have read alot about 4'
exhaust systems from the turbo back. There supposed to increase
power/torque and lower egt. Just wondering if anyone has any pointers
on which system would be the best. What is the best muffler, is 5 or 6
inch worth the extra money over 4'. I would appreciate any help.
See that emblem on your door? The one that says "RAM3500"? See what's
written underneath that? Notice how there's no 'G'? That's not by
More of an EGT reduction that a power gain. You'll get a bit of a bump, but
nothing significant. The real story is in EGT reduction (especially when
coupled with a better intake).
At stock power levels, no - nothing over 4" is beneficial.
As for exhaust kit selection, most any aftermarket kit will come with an
efficient, straight-through muffler. Stainless steel is better than
aluminized, and priced accordingly. However, if you're in any of the colder
climates, the up-front cost of the SS system will pay for itself in the long
run by virtue of it's longer lifetime.
