 Topic: OT-Cummins exhaust
Posted: 21 Mar 2011 at 5:57pm |
I had a Dodge 96' cummins 5.9L swapped  into my 2000 F350 6spd crewcab dually. The 7.3L was getting tired at 272,000 miles. I am most impressed with the pulling power of the cummins 12V coupled to the 6speed tranny & 4.10 gears. My engine swap mechanic had a 4" straight SS exhaust put on it, but I will need some type of muffer. Don't get me wrong, I think it sounds cool hearing the turbo spool up through the gears. In 6th gear, at 70mph it is quiet, but at the 55-60mph there is an exhaust drone that will drive me to wearing ear muffs. Its like a pressure buildup on my hearing. What type of fow through muffler should I have the exhaust shop put into this for more reasonable quieter sound?

MBRP or silverline is what I would go with. I'm rocking 5 inch MBRP with a muffler.
I actually just put my muffler back on because I was afraid one of these mass cops were going to break their neck looking at my truck as I drove by.
By the way, I'm glad to see another de-stroked ford

The exhaust is 4" from the turbo back. It goes all the way over the rear axle then exits at the rear corner. I'll try to get a pic tomorrow. It is straight for a good length(8-9'??) from just below the front of the crewcab to the rear axle (8'bed) before it vertically bends up and over the axle. Then it has a 90 degree horizontal bend around the back of the duals. Would any additional bends in the 8-9' straight area help reduce or remove a drone? Or, would placing a 36" long flow through glass pack do any justice?

That big stack should funnel alot of water down the pipe if you leave it out on a rain storm.

Banks is garbage....I redid the stacks on my buddies Cummins and it was LOUD but he wanted to quiet it down with having a baby recently so I put an MBRP muffler on it....same as my 6.0 has....great sound, but very livable to drive.....and they arent that expensive.
