ok i have been looking all over where i live and i cant find any one who sells the pipe i need to build stacks. anyone know where i would be abls to but 4 inch or 5 inch pipe? also a y-pipe that big? i know i can but a kit for 370-700 but i want to build it myself. and has any one seen a PSD with just one stack or is that a chevy guy thing? i can get 5inch by 48 inch tall at napa for 78 each so i was thinking just some flex pipe up to one stack. thank you for your help

 

www.airflo.com

they even make a down pipe for our truck

 

find a parts store for heavy trucks

 

The way i went was pretty cheap compared to a full stack kit i bought 5in stack kit from black cloud diesel without stacks for $335 and got 10' 5in pipe from carquest for $80 cut 2 36in pieces and put a mitre cut on them and then painted the whole thing with high temp black paint would post pic but dont know how

 

Napa will have/be able to get the pipe you need. t-pipes, clamps and all that.

 

yeah napa was what i was thinking but they only has the 48inch 5inod chrome stacks no tubing. but pure diesel has a 4 inch kit for 289 and 5 inch stacks with a 4 inch end pipe so i may just buy the kit from pure diesel and get the stacks from napa

 

was able to find a few places in new orleans yellow pages that sell truck parts
should have everything you need in 4 or 5 inch
that's where I would look first

 

do what rbaker said. We have a scrap yard for big trucks here and they have alot of good stuff.
