I like the idea of stacks . Where are you guys gettin the best deal on'em. I saw a picture of a set of 6"? that where black I liked those! Any help would be great!

Most of us made are own, but black cloud diesel sells a set. I think theres some one on ebay selling them also, I know that they sell just the stacks for less than $100

i bought two used pipes on ebay for 26 bucks. then i just closed up the ends of a 6" square tube that i got for free from a welding shop, mounted the pipes on top and ran the exhaust in the bottom. its not the most free flowing design, but its easy and functional. especially for what it costs compared the $500+ kits online. i'll try to get some pics if wanna see how it looks.

that's how my last set was built... I saw ZERO difference in spool up or EGT's vs. 5" straight pipe or 5" stacks built w/ a ypipe and elbows.

I reccomend the Y pipe rather than the square tube as it will sound better and probably smoke more even. I got my y pipe from the local diesel shop (can't remember the price) and then the absolute best price I found on the stacks was at a local freightliner dealership.

I think the Y pipe offers more turbo sound... otherwise sounds the same... no difference in smoke

for me the 1/4" thick rectangle tubing was the all way to go. it don't dent and no clamps and straps to hold the stack in place. just mount the tubing to the floor of the bed and all is ridged
