  1. I run a single muffler under the cabin Then thru a y pipe to twin 6 inch pipes up behind sleeper very quite to sit in all day whilst pulling but I've been told by various people that it still sounds good Some say pull the muffler and install a small resonator but its working well for me so ill leave it till time to replace muffler

    Other truck has straight thru single 5 inch behind cabin on the off side

    Sounds great for a short drive but not to work all day

    Just my opinion

  2. That would be about right

    Brand new 631GC5117 turbo as per Mack specs

    All systems good

    Pulling tri axle trailer and grossing 41000 kg. / 90000 lb ?

    On a continued pull I get 28-29 psi

    And surprise a lot of new trucks when I pull past them

    And still get 2.47 km per litre

    Iam happy with that
