those of you with stacks...

[jheyob]

I can strap my old small quad in ok around the stack.

As far as the rain/water problem...When I had a miter it was horrible, I would somehow get soot all over the dash, that should give you an idea of how the roof looked But since I switched to a Cat stack, it's much better. I don't notice soot anywhere on my truck now, and it is a bit quieter than a miter cut. Plus it looks sweet with the smoke shooting out at an angle

Have you guys noticed any soot build up in the bed? You know like how a bumper and tailgate get after a little driving

 

[Turbo Performance]

Not really. The only time I get soot in the bed is after rain or snow. Or at least that's the only noticeable time.

 

[GeorgiaDuramax]

Honestly I don't ever notice any because I keep my truck clean and don't drive it in the rain. But after a wash i've noticed some on the top of the bed sides but that's it.

 

[DMAXchris]

With my truck being white, it always had soot down the bed and all over the gate. Rain only made it worse.

 

[TrentNell]

my truck was black so i never noticed soot , but loved the single stack !

 

[TeaBagger2006]

i know i'm a little late on this thread, but i just wanted to throw in some info from my experience. I've messed around a lot with stack styles and the heights of the stacks. I have found the key to "noise" is height. If the stack is as high as the roof (like mine) you won't hear to much from it on those long highway drives. Don't notice much drone at all really. Now if you have the stack half way or three quarters the way up the rear window, you'll def hear it more. Like i said, i know this is really late, but maybe it will help

I can't really speak for Noise or drone, as I run an S480 single and mine is God awefull loud, But I don't really get much soot over anything, and with the stacks offset from center, but not in the corner the lower tie-hooks are still accessible. I don't haul bikes, but my Outlaw-S fits with no issues.

Here is some pics, as well my avatar is my truck on the dyno with the stacks setup.

Great pics custom, Ive been toying with the idea of running a single 4 inch, kinda wanna stick with stock exhaust size thru out the stack, but little wondering about running no muffler. I have the LB7 duramax. and takes on how loud it would be? also if I wanted to run a muffler (dont really want to) but if I needed to, anyone know how hard it would be to do so.

This post has made me think more so of running stacks. Thanks Chevy

I love my stacks. They are loud as pure hell. You should hear them while driving under a bridge .....as far as the soot goes, anything you tow or haul in your bed on a moderate tune will get covered. It is the biggest pain in the ass. The entire bow of my boat & console had a layer of soot that took days to get out of fiberglass. Be careful not to sit on the tailgate either :thumb:

 

[jonathancasey19]

Oh yea....only thing that irritates me is that the stacks wont smoke evenly. I've checked the t-pipe and it has a little plate that's suppose to distribute the smoke to both but seems to puke out of the drivers side and trail out of the passenger. I might have a video of that somewhere.

 

[MadMooseEngineering]

my stacks are about even with my roof and turnouts turned 45 from the center and i dont get alot of drone. the rain and snow thing you could drill a 1/8th hole in the bend to let water out.

Easy, just put a muffler back on underneath were you have the cat delete pipe. Or if for some reason you still have the cat they make muffler drop in's for the stacks....

 

[MadMooseEngineering]

i have a muffler on mine it just points down before going up to the stacks due to a frame brace being in there. When i change mine to make them look better i want to put a shorter muffler on it.

 

[HogAssWild]

its not bad with a tow tune.. pretty bad ridin a few days with a race tune

Correct me if im wrong, but if I drop the cat I would throw eng codes right?

No, but your truck shouldn't have a cat unless it is a CA emissions truck.

 

[Red]

The truck won't even know the cat is missing.

I think about stacks every time I see them, but I like having my tool box too much to get rid of it. And bikes barely fit with a closed tailgate as it is.
