Stacks question - Flex pipe

[dieselcrawler]

Hey all...

Want to know how your exhaust systems are made... when you put stacks on your truck, do the stacks get bolted to the bed solid, and do you have a flexible section (the braided metal type) in your exhaust pipe some where?

I am making a set of stacks for my K-30, and am afraid I'm gonna break the down pipe or the turbo if I don't have a flex joint in there somewhere. I am going to have to bolt the stacks solid to the bed, so something has to give somewhere...

Thanks...

On mine and most of them it goes from the down pipe to a short section to a flex pipe to a 90 and then up through the bed to a Y and then to the stacks.

Are there any places that sell the flex-pipe seperately from a kit?

I am sure there are. Probably get it at some trucking companies or somewhere like that.

Any big truck parts place should have it. They should have it in many different sizes and lengths

Does anyone know of a place to get a 3.5" diam section I can get? I'd hate to fab it all up, and then break it... and then have to find/install the flex section...

here are some pics from my stack install that can give you some direction

yup, I was guessing that there had to be somthing like this in the mix...

now if only I could find a place to buy 'em... I'm terrible at finding the stuff I need to online... JCWhitney only has up to 2.25" ones, I need 3.5" OD or ID...

check out any of our vendors like Gus at farmboy etc... they should be able to fix you up with a pipe.
