Just trying to figure out what would be for better performance, a standard Banks style setup, or a set of stacks. I'm wanting to make an educated decision here. On one side you have tonnes of proven test data from banks. On the other side you have physics, looks, and the Teamster fleet that says stacks are the way to go. Any help here would appreciated.

I am not really sure performance wise but I did notice a little bit better egt's with my stack but I couldn't handle the drone in the cab it was just too loud.

What's a Banks style setup? Is it just like a regular, underbed exhaust? If so, you won't see any performance gains going from one to the other. It is soley based off personal preference.

If you like stack, go with stacks, if you like the look of a sleeper, or stock, go with that.

A 4" underbed exhaust, and 4" exhaust to a 5", 6" or 7" stack will yield the same performance.

And don't believe the crap you read in magazines about Banks having the best products. It's a straight up lie.

peobryant has a point

I dont know anything about stacks but my gess is besides the coolness is to direct smoke away from people.

Thats the reson why refinaries and powerstations have stacks I think.

It's got the typical 4in underbed exhaust from Banks. Then my questions are why do the sled pullers/performance diesles run the stacks instead of the underbed, they do not have to worry about pulling a bat mobile getaway with the smoke screen to the car behind them. Also why do you think Banks suck. They are pretty bold with their add campaign in the latest diesel power mag. If those figures were false then that would set themselves up for a bankruptcy lawsuit from all of the venders that they just slam in the ad.

Well not to go around brand bashing but there isn't much difference in the normal underbed exhaust systems nothing that you would notice. Banks usually is one of the more expensive brands and personally if your pocket book is big enough to buy stuff there then you might be able to get more stuff from a smaller company for the price.

I am honestly trying to figure out what the best parts and mods to buy and do. How do you know that stacks are the same as underbed and vise versa. Also why do you not like banks. So far to me they are the only ones that I can find to back up their product with viable research. Aside from ATS

hey toy4xchris i tried to PM you, but since I am a newbie I cannot do so

With stacks you will notice a raise in egts (exhaust gas temperature) about 75-100 deg vs a mandrel bent turbo back 4'in exhaust. Stacks look cool, sound good and thats the bottom line! AFE makes an inexpensive 4'in aluminized turbo back exhaust that is just as good as the banks or go to a local muffler shop and they can build u one as well.

Here's some technical answers now! Now, toolboxes and stacks, I've seen a few but is it feesible.

with Banks your just buying the name. Its like a bose system vs a non bose system. They both put out the same performance wise but one looks better, but your just paying for the name in the end...

Sled pullers use stacks because the rules for the majority of pulls state that your exhaust must exit upwards... Some people have an underbead exhaust and when they pull they put a 90* on the exit and a pipe to direct the exhaust up.

Yup! I had an in bed box over my stacks on my 02

any issues with it and the stacks. Thankx rad for the info So aside from EGT's, which if you are worrying about 100 deg then you probably have other issues, there is no difference

Nope!

Preference

Thankx again for the info guys
