Just a note on my up to date progress with my never ending search for the fuel mileage on this 6.7 beast...
I did pick up a 5" Aero Turbine 5050XL Friday locally and even met one of our newer forum members there in the process. I ended up giving the guy a ride in my truck as he said he hadn't heard a straight TBE 6.7 before. He has a new 6.7 and was looking into what he could do and I ended up selling him enough of my old 4" stuff to get him going for 50 bucks...
I figure it was worth 50 bucks and all he needs now is a fooler box and some time to get it all on. Hope to see him on here soon as well. He is one of our younger bucks here LOL.
Anyway, I cut and spliced in the 5050XL yesterday and made a much better hanger right at the front of the rear axle. The Aero Turbine with how nice they look and all I hated to weld just anything on it to get the 5050XL hung so I went to my what seems to be endless supply of junk pile LOL...
For all of you oilfield types out there, you will most likely know what I used when I post all this LOL... I took a flange ring gasket the R-35 series in 316L SS, it was one that was beat up somewhat but me like I am, it might be junk for a gasket, but its great for something else LOL.
I cut it and spread it out into a large U shape and then added some 1/2" rod to fit the rubber gromets hangers under the truck. This all mounted in the same way and place as the OEM muffle did. I just tacked the modified stainless ring gasket to the down stream end of the stainless Aero Turbine. I know its much stronger than how I had hung the straight pipe before and looks better if nothing else anyway.
After Matt's thread on the hunt for the better mileage setup, I thought I would just see if a muffler of sorts with a little more restriction than like the straight through design might help my truck out. Figuring on loosing the noise alright but if I can get a little fuel mileage from that, it would be cool with me.
I will get some PIC's of this all today some time. I have been also as time allows getting some PIC's in my gallery on the forum as well. I have a couple so far and still figuring out how that all works, so far its somewhat less than what I wanted, but in time I hope to figure how to edit these PIC's LOL...
The Aero 5050XL is a big sucker with design what has always worked well with the plumbing I did in the oilfield. It sort of rifles the exhaust as it comes out of the body of the 5050... It did kick the heck out of the noise best that I can tell. But it also got rid of the sound this 6.7 has always had at idle with the straight pipe. I hated how it sounded at idle, it's like the 6.7 sounds at idle like a bad exhaust leak and even worse, somewhat of a burnt valve as well... At least to me the straight pipe exhaust at idle does, now sure, as you bring up the throttle the 6.7 does ring out then LOL, just not so at idle.
Well now at idle it doesn't sound nearly as bad to me anyway. This 5050 did make a big hit on the noise at speeds, one I am sure won't be for everyone here either LOL... I will get the truck out today and do some runs with her to see how the performance was affected or not. Then once back on the route Tuesday, I will know if this brought any fuel mileage up or down while towing.
I hope to see any results on the truck by itself, by the end of this weekend. It will be all town driving, which this darn truck has always gotten better mileage around town anyway. I have yet to figure that one out LOL. One thing I figure though is that if I was to drive on the road and keep my speeds 60MPH or less, I am sure it would be way better than what I usually get...
This part of the world at 55 MPH you have to take a stick and stab it in the ground to make sure your moving... Its so wide open here and ugly right now as the fields are all just dirt with nothing growing in it... So 55MPH is not been an option just yet for me with the 400 plus miles I drive every day on the route LOL... I will post more on the out come of all this later today...
