mack mhe9 Posted April 5, 2013 Share Posted April 5, 2013 This past me in MI. Had what look'd like a plastic pass. Side window with a hole down buy the door lock and hoses run out to a canister on the fuel tank then up to the exhaust?? Quote Link to comment Share on other sites More sharing options...

Lmackattack Posted April 5, 2013 Share Posted April 5, 2013 I have seen some Fuel haulers with a weird looking muffler. Way to big and hanging on the rear of the cab. Wonder how much weight those things add? NO THANKS! Quote Link to comment Share on other sites More sharing options...
umodelnut Posted April 5, 2013 Share Posted April 5, 2013 The big muffler has something to do with all that emissions crap doesn't it? I was at Utica Mack one time and there was a Vision there that had that same muffler. And I think a Granite plow truck had that muffler. Don't the natural gas powered trucks have them too?

LSI Posted April 5, 2013 Share Posted April 5, 2013 (edited) I wonder whats up with that giant muffler? never seen one like that before......................................MarkIt is the DEF mixing chamber that hangs on the frame rails.I see a lot of these on day cabs.It allows you to have a shorter wheel base.I am thinking about putting one of these on my new truck so I can keep my wheel base below 224" with 150gal tanks.I need the space for my APU.Instead of being on the frame its located behind cab Edited April 5, 2013 by LSI Quote Link to comment Share on other sites More sharing options...

rsb502 Posted April 6, 2013 Share Posted April 6, 2013 How's the Superliner running ray? I got quite a bit done on mine today, gotta fix a wheel seal and drill some holes to get all my bolts back in. I got my 3.65's in and my new crossmember, carrier bearing and driveline section finished up. I might actually get to drive it tomorrow if I don't mess around and get some more work done.

That video you made before I watched it about 100 times and added it to my favorites. Couldn't get enough of that E9 music. Quote Link to comment Share on other sites More sharing options...

So know they are puttin them on the back (old style) if you order the truck with clear right side frame railBULLHUSK Quote Link to comment Share on other sites More sharing options...

That set up was first used on the MR/LE trucks. On the twin steer trucks up here the DPF fits nicely between the steer axles. The rest of the junk is hanging behind the cab. The behind the cab setup is bigger and heavier then the frame mounted mixer when you add in the heavy brackets to hold that monster. Quote Link to comment Share on other sites More sharing options...

I was at Utica Mack one time and there was a Vision there that had that same muffler. And I think a Granite plow truck had that muffler. Don't the natural gas powered trucks have them too?Take a close look.The DPF is still under passenger side.The muffler behind the cab is the DEF mixing chamber.
