Next up: Stack and likely a pyro.

Now that I have my Pensacola Diesel reman injectors installed and a slightly used reman injection pump from a 94 E350 7.3 N/A on my 6.9 I see the need for a stack....This thing will roll some pretty serious coal under anything more the 1/2 throttle....Much more than my 91 will let out. As far as I can tell the pump hasn't been played with (yellow paint pen on every bolt/adjuster) but I'm wondering if the rebuilder may have tweeked it a bit.....Let's just say for the 2 runs I made in the truck today tailgater's where not an issue.....

I have plenty of 3" and 4" elbows here along with a 4" to 3" reducer so all I really need is about a 54" piece of straight pipe to close the deal. With the amount of smoke I'm seeing in my mirrors I feel the need to put in a pyro kit to see just how hot the belly of the beast really is.....I ain't complaining -the truck is running/starting great now but this much smoke an an N/A engine irk's me....If my EGT's are good then let the coal roll.....Once the stack is on I will get Goofy to shoot some video so we can compare enviromental polluter's.

Sounds like you are on your way, Ive been planning stacks as well but havent found a good enough deal on the reducers yet.

The baby moose I got from Mel is the same way. Up to 3/4's throttle she pulls hard with no smoke, but once the pedal goes past that watch out cause the storms are rollin in.

I haven't driven it enough yet to judge how much throttle the smoke starts at but it doesn't seem to take much........I'm just going to put a stack on out of kindness to the clown behind me....Having the exhaust dump under the bed causes a tornado of black smoke to follow me - almost like a worn out Jetta.;p

I drove behind mine the other day when a friend was driving and could hardly stop myself from laughing. The exhaust dumps out right behind the tcase. When the smoke starts rolling it looks like a smog cloud and it rolls out from everywhere under the truck.

Its great for tailgaters, give um a little puff and they back right out. Once in awhile it takes a bit more but not often.


Im still debating between stacks or duals out the back. Stacks look good, but duals are a lot more fun when screwing with tailgaters.

I have a 12" space between the cab and dump box screaming to be filled with a stack...

I vote stacks! I'm planning on doing 4" duals with 5 inch tips behind the tires on my truck but yours has the perfect spot for stacks.

A little update, we haven't hauled any serious loads yet, may a ton or just over but it works good....It really works better with the extra weight to keep it rolling......As soon as my Expedition repairs are finished I'm going to fab up a 4" stack for it - video of it rolling coal to come.....As soon as money allow's I will put in a pyro too, I got a free brand new pyro probe from a buddy so I just have to get the appropriate bung and gauge from Freightshaker to suit it.
