stack install 86 f250 6.9 4x4 non turbo
 

I was given two 6inch stacks and was wondering if there was a company that made adapters to put them on.(elbows and reducers)? Thanks
:yeah:

any truck shop should be able to get allthe adapters and elbows u need. you u could make a stack box like alot of people do. i dont like how it looks but does work.

You can find everything you need on ebay too. I've looked many times. everything from size adapters, flex pipe, elbows, stacks, and even clamps. buying individual parts adds up quickly though

just go to your local pipping store and buy the stuff and do it your self, itlll be alot cheaper thats what we did with mine i had to reduce mine from 5 inch to 3.5 i used stainless cause thats what my stack is, its real simple to do if you have the stuff and know how.

I'm getting ready to do mine so I can get you some ideas after I get done fighting it(save you the trouble)

whats a stack box?

a stack box is a 4x4 or 5x5 square pipe that is capped off on both ends, then cut open on the bottom to allow inlet then open on top where stacks are mounted.

thats a stack box.

look in the lets see ur stacks post. sew variations on how to run them in there.

cause im in the process of buying an 85 regular cab 250 4x4 with the 6.9 and i wanna stack it too i was thinkin of doin it the same way isnt that expensive though? where do you get material like that for cheap? i was thinkin of doin single but i was thinkin of duals too

^^^ thanks btw dieselcrawler thats a big help

I used a 5 inch kit off a cummins setup. It was 250 bucks on ebay

u can find em used. i bought all the pipes i needed from truck dealer. cost about 250, minus the stacks, since mine are square.
