Got the EGR delete & new exhaust hooked up yesterday & I love it! I'm really glad I went with the straight pipe rather than the muffler version, its actually still very mellow! NOTHING like a straight piped 5.9!
We only ran into a couple of small problems along the way, the first was threading the Pyrometer bung into the threaded block off plate. NPT threads are tapered so the hole gets smaller as you screw the bung in... Screwing it HALF WAY into the plate is plenty! I went a little overboard with the impact gun & screwed it in 3/4 of the way & it choked the bung down so much that the probe wouldn't fit through it!
The only way to fix this was to use a 1/4" drill bit & a couple of round files to shave enough material off the inside of the bung that the probe would fit through again... sticking a round file in a high speed drill is ghetto as hell but gets the job done much quicker!
When I took the EGR valve off the intake plenum I was appalled by how much suit was built up inside my intake already! With only 3000 miles on the truck there was a good 1/8 inch of suit buildup on everything!
Glad I'm deleting now instead of later! Poor motor!
Here is the pile of EGR garbage that came off the motor.
Along with the stock exhaust...
If you want to get that stock down pipe off in one piece as I did you're going to have to support the transmission with a jack, unbolt it from the cross member, unbolt the back of the skid plate from the other cross member, take both bolts out of the passenger side of the front cross member & one out of the drivers side so you can swing it down enough to get the down pipe out.
Otherwise you can just cut it up with a saws-all but that would be throwing money away!
This is how exhaust was intended to look!
The next little issue we had wasn't even really a problem, just a minor speed bump.
The Flo-Pro exhaust comes with a small pipe section that is only flared on one end, I'm pretty sure that if your truck is a short wheel base you just leave this pipe out, if it is a long wheel base you put this pipe in, but if it is a medium wheel base like my mega cab you have to cut this pipe pretty much in half & then everything fits like a charm! It only took us about two minutes of panic to figure out what needed to be done. Lol!
The one other thing I figured I would mention is that the bigass USB cable for the Pyro controller can be a PITA to get pulled through the fire wall. I tried pulling it through the grommet for the hood latch cable but I've already got too much crap running through there (including 4 gauge amp power wire) so that was a no-go. Then I found the small rubber nipple under the main wiring harness shown in this picture.
If you cut the end of the nipple off it makes a perfect conduit for the usb cable, its still difficult to pull through (lube helps a lot!) but there is a ton of flex in that big rubber bushing so it works good! Thanks Dodge!
That pretty much sums everything up! I love the way this exhaust exits so much that I might not even use the 6" tip I got!
There's a slight drone at 2000RPM but its basically nothing IMO, probably will be worse when towing but IDC, I couldn't be happier!
Here are some snaps of the exit along with a short vid of how the exhaust brake sounds, my brother who is an Iraq War vet says it sounds like an M1 Abrams! Lol
Speaking of my brother, big thanks to him & my buddy Garrett who did most of the heavy lifting while I was messing with electronics. I owe you guys a lot of beers!

The exhaust has actually rotated down quite a bit in the last pic, (please ignore my reflection in the bumper, lol)
I did some "spirited" driving yesterday & I think all the bumps & vibration & such caused this, its so hard to stay out of the go-pedal now!!
Once I get my hands on a Mig welder I'm gonna reset the exhaust & give it a few tacks so it cant do this anymore!
I'm thinking I might go ahead & do the studs before I upgrade the intake/plenum. Its just so hard to not drive it like I stole it!
Might also be taking BigCE's advice & start shopping for a clutch now instead of later.
Thanks for viewing!
