Well after purchasing my truck with allready a few goodies on it and also putting a bunch on in the past couple months ive been thinking about putting some stacks on. I allready have a MBRP Turbo back exhaust but want the looks of the stacks. How many people on here have done them and would you do it again. The way it looks from MBRP its gonna be around $900 in total for the kit and im gonna have a $600 stainless exhaust that is useless unless i can sell it used. Is there also kits that i am missing that re the same as the MBRP System? Any input on the subject would help. As in Ups and Downs of having stacks and companys that make the kits. I was also wondering if running straight stacks would there be a problem with the truck parked in rain or snow conditions?
I have seen a couple of trucks with straight stacks. The owners put coffee cans on the stacks when parked...
Folgers? Maxwell House?
I have fabbed my own stacks from 3 inch pipe, took a couple of 90 deg ells and cut straight down from the throat of the 90. Looked real good. Some folks like 4 inch pipes, though. You can get those at a big truck store.
If you go look in the deisel section which i think you have since you said turbo back then you will find a lot on running stacks. And if your gonna do it go with 6" pipe, looks killer!
I have no experience w/ pickups and diesel engines but I had 6" slash cut straight pipes on a Peterbilt. Every evening, after the truck cooled down, I covered the pipes w/ 2 small plastic buckets. It looked stupid but it kept out the rain and snow.
You don't want that stuff in your pipes as it will go to the first elbow in the system and sit there. Next thing you know,your elbows are rusting from the inside out. Good luck man and post pics when your done!!!
so in extream heavy rain storms ur still ok with straigh stacks? water just evaperates fast enough in the pipes. couldnt u rout a drain pipe at the frist bend?
Yeah, with the truck running going down the road, the water will evaporate. Plus you have to consider, it's a fairly small target for the rain to hit even when it's sitting still, but over time the water will gather when the truck isn't running.
Yeah, I suppose you could weld a bung into the pipe like for an O2 sensor and put a pipe plug in it for a drain.
The only time rain is an issue with stacks is when the truck is parked. When you go to start it, any water that's collected will just blow out.
If you do stacks, go with 5" .... 4" are too small-looking on our trucks, and 6" are too big unless you're lifted quite a bit and are a crew cab long bed. That's what I think, anyway.
This is a diesel you're thinking of putting stacks on, right?
well the straight stacks with the angle cut at the top is what i would be getting if i were doing stacks, but i dont think you can put those door flapping things on the angled cut pipes? i think welding a pipe like an O2 sensor would be good, then attatch a hose to that to rout the water to drain how ever perferd. let the water drain threw that and the exhost threw the stacks. id do 6" but thats just me.
is there a kit that dose 5" all the way from the down pipe to the stacks?
I don't think you would be able to fit a 5" down pipe in our trucks. I just put in my 4" downpipe and it was a close fit. But you could do 4" downpipe then to a 5" all the way after that.
Thanks for all the replies. Yeah the truck is a diesel and is a lifted CC SB King Ranch. I have pics in my gallery. I wanted to put the stacks in and then but my existing toolbox backed up to them so you cant see the pipe going threw the bed. Ill try and post this same thread in the diesel section and see what info i can get but will be sure to post pics if i decide to do it.
