So i have a 15' CHU613 and ive been looking around to see what kind of modifications, whether that be power/tuning, airbag suspension on steers, exhaust from single back to dual sides... or evening putting a #### back window and i only find very very VERY few threads on the internet about these trucks. Only thing i found was an aftermarket exhaust manifold for sale. Its mostly petes and KW's that get the attention. What gives? Dont these trucks have a lot of history? Anyone with a mack that has done these things on here that can give advice? Thanks!

I got a real good deal on a 2000 CH 613 that needed a lot of TLC. Was looking for a single axle to pull a 7 car trailer so I made some major modifications.
As you can see from these pics she started out as a single stack Mack with a small shack on the back. In the end the exhaust was converted ta weed burner (more turn clearance with a short wheel base for the front over hang car), rear window in the sleeper (I did a lot of blind side backing in car dealerships) and slide the front differential back to single it out (saved a bunch of tolls running the NY Thruway daily).
The window was a fairly easy modification using a window kit from a RV dealer. Only thing I would have done differently was use a larger window that opened so that on the nice days when I wasn't idling I could have had more fresh air in the bunk. The exhaust and axle mods required some fabrication but it was more time consuming than hard to do.
Engine mods and such are not very common probably because there just are not as many Macks on the road as the other brands, at least that would be my guess. You may have to make your own special parts if you want to modify your 613.

Rubber duck- I LOVE SUPERLINERS! My dream truck will be a superliner i restore teal colored with orange striping and an orange frame with matte black wheels, bumper, and dual exhaust. I saw an article of a granite mp8 pushing 800hp but they dont mention who did the tune or anything
.
Brian- Oh ok yeah that makes sense since im on the fence on which cat walk to get(steel or diamond) for mine since i do flatbed and its better for me to put the tarps on the catwalk then to keep dropping them and putting them back on the flat when i dont need them and becuase i also use the catwalk a lot.
abyliks- Negative Nancy! lolbrian991219 Thanks this.
