Old CH613 vs New 613 differences

its do able that pic of the raw hide looks like a 06 or 07 thats when they first came out still had e7 s and the same cab dates back to the late 80's only diffrence is the dash 08 and up they made the dog house longer for the mp8 and gave it a volvo kinda dash look

 

air tank set up when they started putting mp8 s in they became pinnacles and also used the 3 small volvo air tank set up


if you would crawl under the blue one I'm pretty sure the exhaust will look like a w900 or 9900 Ih 5" off the turbo going to a belly muffler with dual outlets 4" for clearance around the cab that bell back out to 5 or 6" at the top

 

They've been putting side stacks on the CH/CL and Visions around here right from 2000. (not factory...dealer.)
Pretty easy to do.

 

Sorry I can't tell you what parts are required but I do know the filler panel between the cab and bunk comes off and stays off. So it looks kinda unfinished if you are really looking behind the stack (most guys here used straight pipes with no shields.) Then obviously you need the brackets and pipes.
I do know everything was available through Mack dealer and there was no major modifications or fabricating.
Like I said, lots of guys around here did it after the first time they saw that original yellow Rawhide that the dealer in British Columbia Canada created, then Mack copied.

 

that and you can build it cheaper than mack charges for the package on a new truck
