Started making my stacks today. Here's what i have so far.



I test fit them and they are crazy loud! I'll mount them, but i may have to find some kind of muffler...

 

your making stacks outta 1x4s ?

lol, j/k


looking good

 

How'd you know?

That's 3" pipe. They'll end about a foot above the cab. Painted "Low Gloss Black". The flatbed will get a headboard and sides at the same time. That's what the wood is for...

 

So thats the noise I heard...It is loud....Is that treated wood this time????

 

You gonna do slant-cuts or tractor flappers at the top of the stacks? Or, you can be uber-cool like me, and have slant-cuts AND tractor flappers together

 

Rick, It'll be treated someday...

LCAM, how did you put the rain caps on a slant cut?

I think i'm just gonna put rain caps on the straight cut ends. Might change it down the road.

 

You need to extend the bracket for the rain cap up vertically, then you just bend the arm the rain cap is on. Ends up something like this:

 

Can't wait to see the stacks done!


And I want to see some pictures of LCAM-01XA's truck, make a thread for it

 

thats pretty awesome LCAM! do you know if they make them for 7" stacks? Otahyoni you will really enjoy them especially the sound!

 

I'm hoping that they quiet down after a few times running...

LCAM, That is sweet. More work than i want to do though.

 

Ain't gonna happen Besides, that stack has now been long gone, instead I run a big muffler wth two turndowns before the rear axle, much better on my hearing

They do make them for big stacks, yes, actually I haven't seen slant-cut flappers for small stacks, hence why I made my own to fit the 3" pipe. Heck they even make some flappers that fit inside the stack so from the sides the stacks look open-top but they got the flappers inside them. Either way it's some expensive stuff tho...

Only like an hour really, all you're doing is cutting two pieces of flat stock and bolting them to the flapper's bracket...

 

Coalroller, your truck will be much quiter than mine because it is turbo. I think mine is worse than an open pipe big block...

 

Stacks are really loud even with a muffler, no matter if you're turbo or not. I had to use a muffler and a spiral-flow in each stack and it's still a little louder than I'd like.
