Stack owners...question for ya...

got 25mpg once in my 83.... traveling from ohio to here....

 

[93cc7.3]

Just depends on the wind direction when sitting still but my stacks are flush with the cab

I have a solid rear window in my pickup with 2 5" stacks. So im not sure about the smell in the cab.. But i can tell you with both my IDI and my cummins that my tailgate is always covered in black little dots haha...doesnt really bother me but just something to look forward too

x2 on the soot on your bed. I get lil spots on the sides of my bed if it rained the night before from the water in my stacks. doesnt bother me either. I knew what I was gettin into. Plus its a truck that gets dirty and sometimes I dont clean it for months. I like my truck better when its all muddy and nasty hehe

i couldnt use my rear windows with the first set of stacks i had.5" angled even with the top of the cab.now i have 5" mitre cuts about 4" above my cab.i can open every window in the truck including the slider and get no exhaust in the cab.

they migh be more than 4" above the cab.

lol yup yup same here. yeah the rain has a big factor in the sooty mess.

i cover mine every time it rains. go to the beer store and get some heniken mini kegs. cut the top off them and stick em on. works great.

Im gonna get the miter cut rain caps for mine. Never seen them on dual stacks before only singles that the cummins guys use. I found the rain caps for like 90 a piece at some chrome shop. cheapest so far. iowa 80 wanted like 124 a piece!

19 MPG isn't that uncommon. I got 21 with the Moose Truck and a tail wind a few times.

Last Tuesday I got 80 MPG @ 100 MPH, but that was with a tornado on my *** on US30, tailwind was 125 MPH.

I am going to try and advance the timing tomorrow if its nice enough out.
